Hey, it's Giant Snake from Elder Scrolls Legends.

"Unblockable" is unfortunately no longer a keyword, having been replaced with "cannot be blocked." I'm unsure if there's a way to adjust your line to make that work.

So, at the end of your turn, the hero gains flying and reach, which is redundant (also, out of color unless black has a flavorful reason to grant flying), but also, this only lasts until end of turn?

The flying was a typo Im sorry

"last turn" was probably your opponent's turn, so how often are you going to control a creature that dealt a bunch of damage to a player or planeswalker durign an opponent's turn?

I meant your last turn, I really am bad at formatting, aren't I?

"Can block all blockable creatures." I think that's a tautology. Do you mean "Can block any number of creatures"?

No I mean “can block all creature who don’t have “can be blocked”” so in essence he can block all creatures with flying, menace landwalk and the rest

You keep adding double negatives and such to the ability, and it's very hard to tell what it means. The original text was something like "~ can block creatures with unblockable as though they didn't have that ability"? I think the best way is to actually make it an activated ability rather than trying to describe what it's allowed to block

> {mana cost}, : ~ blocks target attacking creature an opponent controls. Activate this ability only during the declare blockers step and only if ~ isn't blocking any creatures.
