Quoting WotC here: Warp is a new ability that lets cards travel to the battlefield faster than expected. This mechanic has huge implications for MTG, considering that many effects help us take advantage of a creature, even temporarily, and sometimes it'll feel like cheating
GW had a few good Constructed and Limited decks with the mechanic, and the theme was also supported in WB as well
And for Cube enthusiasts, the Arkhive is a solid choice there, too, as the box can also hold 1,000 single-sleeved cards, or almost double that in unsleeved cards if youre a monster
Exert lets you get an extra effect for an unusual cost and I am a fan of unusual costs
MTG: Watch Your Booty Top Five Pirate Commanders Hoist the colors, set sail, and make your opponents walk the plank with these five Pirate Commanders
My version piggybacks off of morph technology and is much less elegant, though not completely devoid of merit: It feels nice to put your 'useless' cards to good use, and starting at 2/2 opens up a few more design paths for the cards
