Whenever Battle Tested Knight attacks or blocks
and does not die, put on it a counter of your
choice from first strike, lifelink, deathtouch,
menace, trample, or +1/+1.
At the beginning of your upkeep, if Battle Tested
Knight has five or more different counters, it
gains absorb 2. (If a source would deal damage
to a it, prevent 2 of that damage.)
