This 2/2 Grizzly Bear has two combat damage triggers, both of which are strong
Open the Graves: Best Artifact Token Generators: #1
A fantastic draw engine, Claydol let you churn through cards, getting rid of the poorer showings, and slowly amassing the best of the bunch in a single hand
The actual amount of damage doesn't change, but only the way the game considers the damage to have been dealt
War Greymon (X-Antibody): Clear the quest "Undead Yard"
Monarchic Perfection X TRAP Continuous Once per Chain, if your opponent Special Summons a monster(s), and you control a Tribute Summoned monster (except during the Damage Step): You can banish 1 "Monarch" Spell/Trap from your GY, then activate 1 of these effects (but you can only use each effect of "Monarchic Perfection" once per turn)
