I guess I'm going to be feedback user now. Please know ahead of time that I'm not the best at judging power levels.
Eh, I dunno about this. Leatherback exists, I know, but I'm not sure if adding one more G equates to a +2/+1 increase.
Huh. Just... ANY counter? Seems just a bit strange, along with the lifeloss triggering off attacking instead of just upkeep. Probably fine though.
What said.
Not entirely sure if this wording works. If it were me, I'd just give the creatures a tap ability.
Needs to be mythic. Also, why is this high platform called a cube?
Remove "the"
Just want to point out that it wouldn't be hard to make it deal the damage only to the defending player. Also, the name "Shieldbreaker" makes me think he'd grant a P/T bonus and trample or something.
>~ can't be blocked as long as it's attacking alone.
There are only a few situations where this wording and your wording are not functionally identical. Also, needs to cost more. Maybe 2U or 1UU. Oh, and it needs to be uncommon.
Seems fine I guess.
I'm kinda having a tough time figuring out why you're even bothering making the colors interact like this. It just feels clunky to me.
Wording taken from Darksteel Mutation:
>Enchanted creature is a Plant creature with base power and toughness 0/1 and has defender, and it loses all other abilities, card types, and creature types.
Part of me wonders why Green wouldn't run something that could recur this from your graveyard.
>Beast Tame
>Doesn't target Beasts exclusively
In all seriousness, this has memory issues.

Not even reading this.
Ugh, OK, changed my mind.
OK, read it. Not really feeling it. You know people would probably just use the -4 twice rather than the -2, right?
