I assume you have a reason, but I think this could get away with being a Boar.

Also, don't use colons for your triggered abilities. They are reserved for activated abilities. "if you call correctly" would be "If you win".

This is not the kind of coin flip card players actually enjoy playing with. It's like one of those high variance cards one would see in Unglued e. g. Poultrygeist.

There as here you get an upside and a downside, where often not getting an upside is already enough downside or vice versa, so doubling down just makes the cards more swingy to the detriment of the gameplay.

Mmm, yeah; these abilities tend to be more fun when it's "Small upside or larger upside" rather than "upside or downside".

Also every upkeep? Don't cast this in a chaos match, or you'll be dead before you get to do anything with it. Really weird that you have to flip even if you can't use it for anything.

Yeah, I don't know why I opted for Peccary over boar as a creature type when I was fine using camel for llamas and alpacas. I can be finicky about creature types sometimes.

I'll adjust the creature to give an alternate upsode.
