Comments Welcome!
After much playing around with Temur, and relatively little success, I have now built what I think is a competant and very fun to play temur deck for under $25.
So the curve starts with Elvish Mystic and Whisperer of the Wilds to try and bulk up my mana base.
Heir of the Wilds is a great 2 CMC creature who stays useful later on thanks to ferocious. Icefeather Aven has a nice morph ability and can also be used to chump-block flyers.
Archetype of Aggression can be useful, especially late game, to protect from chump-blocking. At worst it's a 3/3 for 3, which I consider acceptable. Boon Satyr is one of my favorite cards here. With an elvish mystic, you could get him out turn 2, where he can be a pretty scary threat and a ferocious enabler, or use him to bestow something bigger. His big weakness, of course, is 2 toughness, which is a little lack-luster. Savage Knuckleblade. What a card. 3 mana for a 4/4 with some pretty epic abilities. He's probably the guy you want to bestow with Boon Satyr before dropping a Temur Battle Rage for an 8/6 doublestrike trample swing.
In the four CMC slot we have Polis Crusher, Polukranos, World Eater and Kiora, the Crashing Wave (who is only in my budget deck because I had one from a booster). Polis Crusher is pretty easy to get out turn four, is safe from removal like Banishing Light and Suspension Field (also protects others from it), has a relatively cheap monstrosity ability, and comes with trample. polukranos gets really big, and the removal aspect is pretty nice too. Kiora's plus one is better than it loos, and if you can stall enough to get her emblem out and working, it's gg pretty soon (9/9's tend to hurt, especially if you have Archetype of Aggression out). In fairness though, this doesn't happen very often.
Surrak Dragonclaw is a 5 CMC, 6/6, who protects from control, gives everyone trample and has flash, which means he can be used as a combat trick too (albeit an expensive one). I like him. Heroes' Bane is expensive, but scales so stupidly quickly that it requires an answer soon.
Hydra Broodmaster is a monster who makes more monsters. expensive, yes (which is why I only have 2), but crazy fun to play with.
I mentioned the potential of Temur Battle Rage, my favorite combat trick in rotation right now. Aetherspouts is really my only removal spell, which I added purely because I had them lying around.
Like I said, this deck is nothing super special, but it's fun to play with and cheap to build. I welcome both comments and upvotes :)
