mtg all dungeon cards D&D x Secret Lair Bonus Cards!, Not sure if there are others to be pulled, but these were the bonus I got from each D&D Secret Lair. Reliquary Tower won, but the art on that Delver Mint / near mint condition trading card DUNGEON OF MAD MAGE :

Want me to build a deck around specific commander

Expect to see this card make its way into many standard decks

Beastly Card Draw Once you've cast Ruby, a few ramp spells, and finally have enough mana to start casting your big creatures, you've probably only got two or three cards left in your hand, which will limit the amount of pressure you can apply no matter how big a monster you cast

Saw in Half, which comes in the same drop as Deadpool, is another great option in this vein

Cavalier also has a great death trigger that combos incredibly well with an enchantment we'll look at later

"Destroy" effects are far from the most reliable removal in a format like Modern, but there's a lot to be said for any card that replaces itself, especially at this cheap a cost
