one piece the card game Summit War Power Pack Understanding the Rarity of One

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

Why not all three, making a perfect storm of value, either if you find this card in a pack or purchase it on its own

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

Some of these cards can change which side is in use once they've already been played, via the Transform mechanic

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
