best graveyard deck yugioh Pojo's Yu-Gi-Oh! Card of the Day Graveyard Deck • 550+ reels

Amusingly, your opponents will probably need a non-creature spell to take it out, so you might get one last draw on the Sentinel's way out

This card might still see some play in decks that can expect a two-mana discount, particularly ones that arent satisfied with four Murderous Riders

Trading your worst creature in a format where 90% of your creatures were bad for your opponent's best creature when they might have 2-3 good creatures to win with cannot be undervalued

Add on top of that evasion, ward, and getting a +1/+1 each time Valgavoth triggers that card draw, and you've got the perfect commander to build a red/black deck around.

that opponent's monster loses 1500 ATK until the end of this turn

It is still substantially better than "can't regenerate"
