Spider-Man will of course contain many Spiders, but a lot of the deckbuilding hooks for those characters will key more into the Hero creature type
Entomb sends any one card from your deck straight to the bin, where you can use reanimate effects to accelerate your board development
The second auto-ability dulls the Terra card at the point when effects are resolved
As for the card, it's a copy of Akroma's Will, an instant that lets you choose between all your creatures gaining flying, vigilance, and double strike, or lifelink, indestructible, and protection from each color until the end of the turn
Ill break down each color (which will include multicolored and colorless), pick a Top 3, and give the color a grade
Imperial Recruiter Red doesnt have much in the way of tutors
