one piece the card game Summit War Power Pack The 2000s One Piece Card

The One Ring Legendary Artifact Indestructible When The One Ring enters, if you cast it, you gain protection from everything until your next turn

When you play against a deck with a high density of removal spells, waiting to cast Pack Rat until turn 5 is just insane because it forces them to have two removal spells immediately

With synergies for +1/+1 counters everywhere, your board will grow out of control

In this example, I use [c]Augur of Skulls[/c], a 1/1 with regenerate to block [c]Raging Redcap[/c], a 1/2 with double strike

That said, Id prefer a commander with more than a single ETB effect, especially if that effect wont be too impactful until later in the game
