- Converted Dodecapod, Loxodon Smiter, Obstinate Baloth and Wilt-Leaf Liege from keywords to replacement effects.

- Added DiscardMeByOpp param and applied to relevant cards (I've prioritised from 1 - 3, 3 being most dangerous to discard, but priority checking isn't actually applied yet. Plan to expand when I have more free time).
