Suck it blue - Gruul is the color of
Tidings now. This is a sorcery, and it's "impulsive", and its in colors not well built to capitalize on a huge five CMC draw spell, but man oh man is that a lot of cards. The exploration effect is relevant for a "Big All-in" deck, too, providing ramp and helping ensure this is a "draw lots" even if you end up hitting a bunch of lands. This is an instant staple in Commander, but I also suspect it's powerful enough to see play in Standard - seriously, that's just a dumb amount of draw.
