Fantastic concept! These guys seem to make a great duo, they would bring great energy in-game. They look cute and friendly (as well as mischievous) and that's just lovely. That'd make them different from all other cards so far. Dr. Boom, for instance, summons a couple of Boom Bots who are cool and fun and all, but this is something else, character-wise.The mechanics seem a little strong, perhaps the bot could only activate at the start of it's owner's turn (if you don't have minions for it to run suicide into, it's 4 more damage for your enemy's team). But you and your friend (who I read made the stats) both did a great and Hearthstone-appropriate job, this is just a detailI'm sure such a card would fit the game excellently, again, it has great energy and character to it.If you feel like it, you could even write the Summon/Attack/Death emotes for both cards in the description, could be fun. But anyway, keep it up!
