oliveoilonyaasscureshemorrhoid on Counting Counters

Welcome to mtg, dude! my first concern is the mana base, if you down have any pain lands (Llanowar Wastes, Caves of Koilos, Brushland), Sandsteppe Citadel should your only land that comes in tapped. good land count though, usually mtg decks have a 33% of lands, but I would consider more swamps and less plains, with forests staying high (especially with the Verdant Automaton's activated ability). I would take out Renegade Map, it does mana fix, but it doesn't ramp (consider Wayfarer's Bauble, Expedition Map for a good nonbasic land, or Sakura-Tribe Elder). And for combos: consider Barren Glory with Renounce, Spy Kit with Cornered Market/ Rememberance/ Pack Hunt. Also consider Tower Defense, Ranger's Guile, Heroic Intervention, Blossoming Defense, maybe Bonds of Mortality if you put in more removal, Young Wolf, Ghave, Guru of Spores. And if you like abzan colors, check out Fungal Growth. Plus I prefer the commander format over standard, there's lass turn 0 win assholes with Leyline of Anticipation, Lotus Petal, Mana Crypt, Show and Tell, Omniscience, Enter the Infinite. Hope this helps! If you or anyone else needs more help or have any questions, I'm always here.

I think this deck needs sone duals. Godless Shrine, Isolated Chapel, and Caves of Koilos are great budget options!

If you want to go aggro, I'd recommend swapping your duel lands for the pain lands from Origins (i.e. Caves of Koilos). If you are focusing on counters, Hardened Scales and Kalonian Hydra are must-haves. Another fun card to play with is Primordial Hydra. Other cards are (in no particular order) Ainok Bond-Kin, Elite Scaleguard, Retribution of the Ancients, Scale Blessing, Sight of the Scalelords, and Tuskguard Captain. Have fun!

Hello everyone!

I will be heading off to medical school this August and am looking to make some extra cash for this summer (I have to put down a hefty deposit as well as pay for travel as I look for a place to live).

I have decided to part out my modern Affinity deck, as well as my modern Eldrazi hate bears deck. All cards are in practically near mint condition and I am willing to ship/sell in the manner you prefer. I will list some of the money cards below (I try to beat tcgplayer lower with my prices and prices will be listed per each copy of the card).

Affinity PiecesBlinkmoth Nexus x4 ($2.50) Modern Masters 2015

Master of Etherium x1 ($2) Shards of Alara

Etched Champion x3 ($2) Modern Masters 2015

Leonin Arbiter x4 (1.50) Scars of Mirrodin

There are also numerous "4 of's" of bulk rares from each deck that I would be willing to sell cheap but I would need the sale to be worth the shipping. Caves of Koilos, Flickerwisp, Tidehollow Sculler, Wasteland Strangler, Memnite, Ornithopter, Signal Pest, Vault Skirge, Darksteel Citadel, Cranial Plating, Springleaf Drum, Galvanic Blast, Thoughtcast

That's the horrible part for running a 5C Commander... there really is no cheap option for the mana base. In order for the deck to function on just a basic level, you need so many things.

So, first things first, you're probably gonna want to run each of the signets:

Azorius Signet

Boros Signet

Dimir Signet

Golgari Signet

Gruul Signet

Izzet Signet

Orzhov Signet

Rakdos Signet

Selesnya Signet

Simic Signet

This allows you to filter any color of mana into two others. Honestly, this is the cheapest your gonna do for mana fixing.

Another artifact you may want to consider is Mycosynth Lattice. Not only does it make all your cards castable for just their CMC, it also has great synergy with Hellkite Tyrant for a complete win against every player at the table.


You could go with the Pain Lands. While they are cost efficient, they are definitely on a lower tier than other lands:

Adarkar Wastes

Battlefield Forge

Brushland

Caves of Koilos

Karplusan Forest

Llanowar Wastes

Shivan Reef

Sulfurous Springs

Underground River

Yavimaya Coast

You can tell they vary considerably with the cheapest being under $1 and the most expensive being upwards of $20. The big problem here is obviously that these guys hurt you to get that color of mana you need.

The other lands I would suggest would be Mana Confluence and Spire of Industry. With all the artifacts you'll be running Spire will almost always be tapping for any color. Confluence is self explanatory.


There are a ton of other suggestions I could give, but those are the ones that just pertain to the mana base. As a side note, you could also run the Shock Lands like Blood Crypt, but they tend to be more expensive. They are probably better than the Pain Lands in that they don't have to hurt you to produce mana.

Hope that helps!

Yeah. Short of a Scrubland (which I definitely don't have), Isolated Chapel is about the best I could aim for. For now, I'll have to content myself with Caves of Koilos and Scoured Barrens.

Ditch Gnarlroot Trapper and put in Elvish Mystic; mystic is just generally better. Another way you can take it is like I did. (take a look at my deck) Since you use lots of blink cards I would recommend Servant of the Conduit and Aether Hub so you can produce all the colors you may need. I would remove Beastcaller Savant for the servant.

Here's my frontier deck if you'd like to take a look: An Elvish Frontier.

Skybolt, I don't mean to sound mean, but you're incorrect. Caves of Koilos and Llanowar Wastes produce the same colorless mana as Westvale Abbey  Flip or Crumbling Vestige; the only thing that changed was the image they use to show colorless mana.
