This type of effect is most powerful in mono-black, where you'll have a lot of Swamps to play with, but can also be very effective in simple dual-colored decks
But anyways ignoring the fun aspect of gifting, the whole mechanic is largely flavor text to most cards
Best Devil Payoffs Devils are great aggressive and chaotic creatures that can benefit from other aggressive accelerators like Grand Warlord Radha, Runaway Steam-Kin, and Legion Loyalist
An aggro deck that wins by attacking with creatures should probably be coming in at 30-40 creatures
If we get to play it on turn zero then thats just extra gravy on top
One niche upside of this card is that it forces opponents to search their library (even if they fail to find), and theres at least a few commanders that care about that (Im looking at you, Obby)
