pokemon emboar card 33/236 - Sun Moon Cosmic Eclipse - Rare - Evolution Lot Mega Emboar ex Emboar - White Flare (WHT)

It's strikingly similar to Mischievous Mystic, but tokens that sac for mana are much more useful in environments like Commander

Any power- or toughness-modifying effects (those that give +N/+N, for example) and counters will apply to the creature's new base power and toughness, even if they started to apply before Vedalken Humiliator's ability resolved

While her other side does a lot of work, and the taxing ability on the front side can buy you some time, I think she rides the line on playability here

Thats because you can pay one life and sacrifice a creature to put a -1/-1 counter on up to one creature and draw a card
