mikexbustillos on BEAMSPLIT THIS SCRUBz! :@

1 week ago

I tested a couple games just now. There are a couple problems that I see.

1) Your entire gameplan is based on Beamsplitter living. Unless you can always have a Dive Down in hand, and always leave mana up to be able to play it, this game plan is super vulnerable to removal. And almost every deck plays removal.

2) There are only 6 actual win conditions, 4 Beamsplitter and 2 Electromancer, and they all require a lot of other things to line up to be good. If you don't draw any of these, your hand is essentially dead.

3) Gravitic Punch doesn't combo with Beamsplitter Mage because it also targets a player, so I'm not sure this is a great card in this deck. Something like Cosmotronic Wave might work better at getting a bunch of buffed attackers through.

4) The deck lacks resilience in the long game. After turn 5, I was out of cards and had no way to refill my hand. Maybe consider some kind of advantage engine--Firemind's Research or Experimental Frenzy to give you a way to keep going when your hand is empty.

.

I think that you might want to consider A) diversifying your threats, and B) decentralizing your gameplan.

Maybe run some Runaway Steam-Kin or Wee Dragonauts or something as well--they take buffs well and can win games even if you don't draw your Beamsplitter. Plus if you ever get Beamsplitter + Quasiduplicate to happen, you can have some good copying targets. I mean, I'm all for making a bunch of Beamsplitters, but at some point you do want something you can kill people with. (Also, be advised that the Beamsplitter ability triggers on cast; if you had 3 Beamsplitters, for instance, and cast a Sure Strike, you would be able to buff 2, but not keep copying it to all of them, because the copies are not technically "cast." Therefore, having multiple Beamsplitters is not necessarily advantageous.)

Maybe run some more removal spells? A set of Lightning Strike seems like a good addition, to help you get rid of blockers. Maybe a few Fight with Fire in case you find yourself facing a Lyra Dawnbringer.

Just a couple suggestions. The Beamsplitter combo is sweet! I'd love to playtest it again after some updates.

Good luck!

Thanks Kizmetto.

Yes, this is the deck that I'm planning to take to WNM.

I have a lot of the cards but I need to get off my arse and build StuBi's Fermentoring deck before we can play.

I did have a BIG think about Cosmotronic Wave.

Its 4CMC plus the fact that it would be very situational (to get the most out of it my Opponents would need a few Creatures on the field - which they usually don't by the time I've finished killing all their stuff - and I'd have to wait until I could hit for lethal ... then just have Settle the Wreckage cast against me) made it less appealing.

With the amount of flying Creatures and burn spells in this deck usually the last points of damage are fairly easy to achieve.

Certainly not a bad idea, though.

I keep coming back to this list. will you build it in paper? im just very excited to learn how it performs!

what do you think of Cosmotronic Wave in sideboard for alpha swings and alpha striking? But i do like your reasoning for shake the ground and chainwhirler.

Draw well!

I think if you are going down on white cards probably lean into blue a bit. This might even out the manna base till you get Hallowed Fountain. So four of Mist-Cloaked Herald. Then you could also include Siren Stormtamer as a way to doge removal too.

What do you think about boarding Negate to deal with Teferi, Hero of Dominaria and Settle the Wreckage?

Not sure it this works but Cosmotronic Wave could be a sweet finisher at that 4 cmc spot.

It might not be a bad idea to consider Cosmotronic Wave, from Guilds of Ravnica, The card could help get around any blockers that a Shock or Lightning Bolt won't handle, plus if you go up against a token deck this would help remove any 1/1 tokens.

ok ive done this deck before but definately drop Grazing Whiptail to at least sideboard, if not cut completely and run 4 Circuitous Route. drop Polyraptor to a two of, since you are gonna tutor it up anyway with the forerunner.

with no indestructible, best you going to get is 8 raptors per 1 forerunner. adding in assure/assemble gives you an indestructive outlet to target your forerunner to make many many dinos. I alsp reccomend filling those two empty spots with Regisaur Alpha so those polyraptors can swing asap! do be careful of Settle the Wreckage though.

over Shake the Foundations how about 2 Cosmotronic Wave? clears tokens and allows alpha striking! the other 2 slots could be 2 Drover of the Mighty and if you dropped 1 forerunner and 1 otepec huntmaster to then complete the set.

i think this will allpw you to ramp well into polyraptor this way.

hope the comments help! here is my polyraptor combo deck for reference

Thank you for the suggestions wonderboyrox, but I really don't want to drop the cash to Jund 'em out. Part of the appeal of this deck for me is that I own all the dual lands I need, including Stomping grounds once the next set drops. I have another Banefire that I'll probably end up putting back in, but I wanted to test out Cosmotronic Wave which is a wincon in its own right with a decent boardstate.

Wonder if Cosmotronic Wave would be viable. It would be a nice one-sided board wipe for a bunch of small creatures and/or help push through that finishing damage.
