MacKinnon, Avalanche's Fury

Trample
If a red source you control would deal an
amount of noncombat damage less than
MacKinnon, Avalanche's Fury's power to an
opponent, that source deals damage equal to
MacKinnon, Avalanche's Fury's power.
When MacKinnon, Avalanche's Fury dies,
return it to the battlefield tapped and transformed under its owner's control.
