Assemble The Legion.

At the beginning of your upkeep, put a muster counter on Assemble the Legion. Then put a 1/1 red and white Soldier creature token with haste onto the battlefield for each muster counter on Assemble the Legion.



Looks kind of cool. 5 mana is a lot, Cool flavor though.

Might be cool in EDH, but it could really fit on 4cmc, instead of five.

Boy

This escalates quickly

But yeah, I don't think this'll be Standard material.

It's a 5 mana do-nothing spell, unfortunately.

I would consider playing one in American/4 Colour control, but the biggest problem is the fact that the buggers don't fly.

Oh, and it'll never beat Filibuster counters.

Agree with Chris. Filibuster counters > Muster counters. I mean, filibuster counters are awesome.

Probably too expensive and too slow for Standard although it really does scale very quickly when it gets going. I assume the only format it'll see play is in EDH (but it's pretty awesome in EDH).
