I mean...thats ok. I didn't mean to offend with "dumb", sorry. I just feel like that effect, on that body, at that cost, at that rarity is just not worth it...like ever. Maybe if there was some kind of untapped matters theme, which would make it a cool build around. Otherwise, the only time it's useful is if you're ahead in a race...at which point it just gives them another turn to stabilize over some hasty creature/removal/solid body without a semi-drawback.
it's relevant any time you're in a race. if you're behind it gives you some catch-up damage through a free, safe attack step and cuts them off from effective retaliation. if you're about even it helps pull you ahead through the same mechanism. if you're ahead it's risky 'cause you give them more time, but then you just don't swing and use your 4/4 blocker to control the speed of the race to your advantage.
Behind...you have to risk your probably relevant 4/4 to make them skip, how often is it better to prevent one attack than to have a 4/4 blocker when you're behind.
you seem to have forgotten the damage prevention ability.
Granted, given skill you can use this to your advantage, but I don't think it requires any cleverness or additional skill. Having it be one-sided at least tests the player's judgement.
having it be one-sided just makes it an easy swing.
bottom line is you don't play it as
fomori nomad, because it's not that. it's its own thing, but that thing can make a huge difference in the right situation.
