This and the Green Koopa are the basis for Luigi and Bowser's effects. This was the first card I made after Mario, and was the direct inspiration for Bowser's effect. Pretty balanced IMO, though I can only imagine how much rage one would acquire when they find this basically gives cards like Ghoul a free effect trigger every turn XD!

King Bowser

I get it, I get it. It's a 3/3 Charge for 5 with an effect that's pretty under powered. Personally, I did this on purpose. I just don't think I can accept him being very much stronger. His 3/3 stat just works perfectly for me, and being a 5 drop means he can be put out fairly early. Maybe I could give him +2/+2 instead, but I'm not sure if he'd be OP like that...
