Liza's ability gives absolutely bonkers value, but it's ruined as soon as you try to deal with the tag you take. I tried it in a tag me build and I was amazed how I absolutely destroyed all vegan matchups. I made a meta call that people wouldn't be playing a lot of meat damage and took it to a regional.
I was dead wrong. Literally.
Deck went 2-3 beating all non-kill decks I faced.
