Leprechaun Ward may be the strangest deck in 93/94, but it's probably also one of the most fun decks. Especially if you like playing cards that no one else are playing. So let's dive into what the deck is all about; the foundation of the deck is to play a lot of green and white cards that synergizes in different strange ways. One of the more important cards is Circle of Protection: Green, and yes you heard right, green(!). The plan is to cast the COP: Green and then protect yourself from the opponent by making all his stuff green with the cards Lifelace and Aisling Leprechaun.
You can also use the card Green Ward to give the Leprechaun protection from green so that it will never die in combat and just continue to make all of you opponents creatures green. This should make you able to repel the opponent’s creatures quite well but of course you also need to win. One way is to use Force of Nature, as it only has a upkeep cost of 1 if you have a COP: Green on the table. And who knows, maybe you Leprechaun have turned all of your opponent's creatures green, then you can just put a Green Ward on your Force of Nature to make it "unblockable". How does that sound?
