So I have seen many LoL based cards floating around here and there, I figured I would make a few. Some go with original game features, others based on fan fiction.
Nunu, Wrath of Winter - the funny looking mana is a legitimate type called snow mana.
Xin Zhao, Great Rider - creatures with horsemanship can't be blocked by those without.
Baron Nasher -Rampage 3= creature gets +3/+3 for each creature blocking it beyond the first.
Fizz, Void Trickster -The return to hand ability is his shark, bouncing them.
