Notes & Combos

Honestly at this point I'd sub out a nib for a heavenly prison if I had one because I lost so many games to The First Darklord summoning and chainblocking the fiendess play. The only extra deck card I ever used wwas knightmare phoenix, but it was really situational.

Replays

For replays check invalid url most of the climb was documented, I think I started with adamancipators and then switched to subterror around Leg 1 or 2.
