Tetsutetsu, Kind n' Chivalrous

Haste, Indestructible
Tetsutetsu enters the battlefield with {x} Iron
counters. For each Iron counter, he gets +1/+1.
Iron Deficiency (At the beginning of your post
combat main phase, remove an Iron counter from this permanent. When Tetsutetsu has no Iron counters on
him, he loses Indestructible.)

heard you fought some villains and I came to see if
that was true! But you're just a bunch of brats that
think you're better than us!"
