Regisaur Alpha Discussion

multimedia on Goreclaw's Unsealing

1 day ago

Hey, I like this version of Gruul Unsealing for post rotation because I think Goreclaw will be much better then.

Consider Steel Leaf Champion? Three drop who can trigger Unsealing and has great interaction with Llanowar. Just having 4x Llanowar and 4x Champion in the same deck can give you opportunities for a turn two Champion. This play alone can win games. Goreclaw can't reduce Champion's mana cost, but it can give it a pump and trample which is very good.

Consider Regisaur Alpha? Alpha is a better five drop with Goreclaw and Unsealing than Glorybringer. Alpha puts more power on the battlefield which is good with Ghalta. Glorybringer is much more difficult to make than Alpha because the majority of the deck is green with many creatures who are double green.

There's only one main deck creature, 1x Ghalta, who can trigger Unsealing's second ability. I see Tyrant in the sideboard why not just main deck Tyrant? Not taking enough advantage of Unsealing's second ability in the main deck. It's what makes Unsealing a busted Magic card. Consider more 7+ power creatures? Consider more Ghalta? Ghalta is the finisher Dino that has the most busted interaction with Unsealing since you can possibility cast it for only two green mana.

I see too many 4 ofs here, cards that are not as important as Unsealing, Llanowar and Goreclaw. These three are the set-up cards for the strategy, everything else wants to come after them. You want to consistently draw and be able to play Unsealing turn three or four. The way this deck is currently constructed this will difficult to do. I suggest trimming or splitting the numbers of lot of cards.

Here's an example:

  • 4x Llanowar
  • 4x Champion
  • 2x Rhonas
  • 2x Prowling with more in the sideboard
  • 4x Goreclaw
  • 2x Ripjaw with more in the sideboard
  • 3x Alpha
  • 3x Ghalta
  • 2x Tyrant

  • 4x Unsealing
  • 3x Abrade

  • 25 Lands

You can use the sideboard as a means of splitting the numbers of some cards between the main deck and sideboard that are good in some matchups, but not as good in others. Prowling for example is great in control matchups, in matchups where you have to worry about counterspells, but don't really need it any other matchups. Ripjaw is the same, Unsealing and Goreclaw are more important four drops therefore split Ripjaw between main and side since it's good in aggro matchups. You can take out some Goreclaw in aggro matchups for more Ripjaw since Goreclaw's three toughness is problematic against aggro.

Find a spot for Helm of the Host. It could combo well in this deck.

regisaur alpha and Etali, Primal Storm are prime subjects for dawning the helm. If Regisaur wears it, you'll get it AND another trample dinosaur each turn. They'll both have haste! With a Forerunner of the Empire on the battlefield, you could either put the helm on another dragon and chip away at the opponent each turn OR, if you know you'll be playing dinosaurs, you can put the helm on Forerunner and deal more and more damage each turn.

Deathgorge Scavenger would give you consistant life gain, but that's not quiet as good. If you have a Regisaur on the battlfield, you could opt to give each new Deathgore +1/+1 and swing with haste, but... why would you not put Helm on Regisaur???

Rhonas the Indomitable would LOVE the helm! The second Rhonas will activate the first Rhonas and they can buff each other!

While equiping Otepec Huntmaster and Kinjalli's Caller would theoretically make dropping big bombs gradually easier, this is a silly idea. The helm requires almost as much mana as your bombs anyway. By the time these combos would be up and running, you would have a dinosaur on the battlefield who is a better target for the helm. These combos might do well in a commander deck though. Your commander tax wouldn't matter!

Hey, Sarkhan's Unsealing has a lot of potential with Dinos. Five of the better Dinos triggers Unsealing: Ripjaw, Carnage Tyrant, Gigantosaurus, Regisaur Alpha and Ghalta. Ghalta, Tyrant and Giganto are very good because they trigger Unsealing second ability which can potentially board wipe only your opponent's side of the battlefield as well as do 4 damage to your opponent and all Planeswalkers he/she controls.

Unsealing triggers on cast this gets around counterspells and removal. Even if the Dino you cast is countered if it's power is 4 or more then it still does 4 damage to any target. Any target is a reason to play Unsealing it means you can target a creature, your opponent or any Planeswalker your opponent controls. Because it can target both creatures and Planeswalkers makes it a great main deck card since it's good in both aggro/midrange and control matchups.

For the manabase consider 4x Timber Gorge? I suggest Gorge over Sheltered Thicket because it looks like other than Abrade you're building Dinos for post rotation. You need more than only 4 sources of red mana in the manabase. I suggest 4x Crag, 4x Gorge and 4x Mountains to be able to consistently play Huntmaster turn two.

Consider 4x Llanowar Elves? Dino's like ramp and there's no better ramp card in Standard then Llanowar. 15-16 Forests is good reason to play Llanowar because consistently you'll have a Forest to play him turn one. I like Drover as a two drop mana dork more than Huntmaster because mana created by Drover can be used to cast nonDino spells. I also like Thrashing Brontodon instead of Raging Raptors. Raptors are lackluster without having an enrage enabler so you can take advantage of the land ramp. The four toughness of Brontodon is good for a three drop as well as it's abilty to sac itself to remove an artifact/enchantment which is handy to have for lots of matchups.

Consider this Dino creature base:

  • 4x Llanowar
  • 4x Drover of the Mighty
  • 3x Brontodon
  • 4x Ripjaw
  • 3x Alpha
  • 2x Giganto
  • 2x Tyrant
  • 2x Ghalta

Consider this other spells base:

  • 4x Unsealing

  • 4x Commune
  • 4x Abrade

There's some Dinos that go well with a sideboard plan. Runic Armasaur and Deathgorge Scavenger. Both have narrow effects which makes them better as sideboard cards than main deck cards. Other sideboard cards to consider are Banefire, Magma Spray, Savage Stomp and Vivien Reid.

Good luck with your deck.

Welcome to the format! and yes, Dinosaurs are awesome.
I'm not sure what kind of meta you are going to play in, so some of my suggestions may be moot, but here are some quick thoughts on my first look:
You need more bombs. Etali, Primal Storm, Zacama, Primal Calamity, and Regisaur Alpha are all probably must haves. Your commander puts dinos on the field, so running all the low cost dinos means you've got a great curve, but you won't have the power to end games.
You'll find planeswalkers underwhelming in most commander games, and the two you have don't synergize with your wincons effectively.
If you can get your hands on a Vandalblast do so, you will probably want some more artifact and enchantment removal.
Your ramp looks solid, but is excessive for your curve, if you add the bigger bombs, this should be fine.
Lastly you need a little card draw, not much cause you want your commander to bring your big dinos in, but something like Elemental Bond can really keep you moving.
Good Luck!

I'd suggest cutting a few or all of the Knight of the Stampedes because you're already presumed to have 4 mana at the time that you play one. The turn after if you can make your land drop you already can play regisaur alpha which is at the top of your curve. (Besides kicked Territorial Allosaurus) So the 2 mana discount doesn't really end up doing much and you're left with a 2/4 body for 4, which is pretty bad.

Agree with swimtothemoon's suggestions about Traverse the Outlands and Aura Shards for later upgrades.

My other thoughts are that you might want more haste effects to let Gishath and others drop and swing the same turn, and that you might want to add more card draw or card advantage in case Gishath gets imprisoned somehow.

Also a possibility are damage-dealing board wipes, which would trigger enrage and possibly not even clear all your own creatures.

I agree with 22edinkel, Abundant Growth doesn't add that much to the deck. Sure, it cantrips, which isn't super bad, but there isn't much upside other than that. You only need the mana fixing for the one off-color card in your deck (Gishath), plus you already have Utopia Sprawl and Birds of Paradise, which should be more than enough in that regard. It's not really worth playing over something that would add more devotion like Wistful Selkie (which isn't on theme, but is really good for devotion). You could even add more payoff cards in its place. Have you thought of playing Green Sun's Zenith? It's really awesome in Green Devotion, you can play everything in your deck and with Regisaur Alpha you'd win on the same turn with hasty dinos.

22edinkel I was looking at Ghalta, Primal Hunger is a good card. Only thing I didn't like is if i didn't have a board it's hard to summon.

As for regisaur alpha he's been super solid and definitely worth it. I am splashing red for Kessig Wolf Run and Blood Moon

Abundant Growth is in there to help with replacing itself and devotion. I see most decks use Oath of Nissa but thought growth was better for this build may be wrong
