Staff of Compleation A 3-mana rock that uses your deck's primary synergies is an acceptable card for casual Commander decks, but Staff of Compleation does much more
Youre in luck, as Ive found the most valuable cards and sets that you can get from this series, drawing upon my years of experience as a casual Pokmon TCG enjoyer and intensive market research
Bad Primes that easily go for 1 pack include just about everything other than Donphan, Mew, Magnezone, Yanmega, Gengar, Typhlosion, and maybe Kingdra
However, I will enjoy seeing it in the wild
Using the Mardu mana combination of red, black, and white, this deck focuses heavily on bringing cards back from your graveyard for a second chance at doing damage to your opponents, and the Commander even mills two cards every turn to try and put some spicy creatures in there for them to bring to the battlefield later in your turn
That damage can stack up very quickly if wheels start flying, though, so dont be afraid to put it into any deck featuring them
