Fellmedn, the Hammerbind

Indestructible, Hexproof
Start the game with Fellmedn in your sideboard.
At the end of each game, you may choose to save
up to one Keyword or Ability that was stored into
Fellmedn. You may carry it over to the next game.
If you do, when Fellmedn is called for the first
time in the next game, It does so with 2 recharge
counters.
At the beginning of your upkeep, remove
a charge counter from it. Fellmedn cannot
store abilities while it has charge counters.
