Tiger-Tribe Hunter 3RR
Creature - Human Barbarian (Uncommon)
Trample Pack tactics—Whenever Tiger-Tribe Hunter attacks, if you attacked with creatures with total power 6 or greater this combat, you may sacrifice another creature. If you do, Tiger-Tribe Hunter deals damage to target creature equal to the sacrificed creature’s power.
Important to note that Flinging your creature happens before damage is dealt. Really useful if you need a specific blocker to trade with one of your creatures.
