I don't think this qualifies for the theme, also just a broken card. Would be an auto include in every deck and for a start of game effect that strong there is no downside.
This is what Im (most likely) going with; my original version had it with negative attack that healed for that amount then copied its abilities to a random minion, but that mechanic I felt is inherently broken and not satisfying to create.
It's a fair card, like the idea of giving it the mech for paladin synergy. Would prob raise it's attack by 1 or it's mana down by 1 since it's not the most threatening mob to come back, especially with silence or morph effects.
What are your thoughts on balance? I mean an aggro deck wouldn't complain about their 3/2 turning out to be a 6/2 instead, but a control or value deck will be sad about a Ysera or Blastmaster Boom turning out to not have any (Battlecry) effect, so should this minion be bigger (and therefore more expensive)? It is a pretty good removal tool by itself^^
Not sure how many entries we will get with the expansion just hitting but here goes for a nice theme.
