I never noticed how well support works with
Willbreaker. Perhaps I might just make a deck out of it. This looks like a lot of fun, but might I recommend not playing
Nivix Barrier? It's slow and clunky, and while it will grab you an attacking creature, it is a lot of work to keep up five mana for that, especially when you want to play
willbreaker that turn. Might I suggest
Send to Sleep? It taps up to two creatures and is a good pre-combat trick if you are having a tough time dealing with aggro decks.
