That's because this combination gives you access to four colors and two commanders with generically powerful abilities
At the beginning of each players draw step, that player loses 3 life, searches their library for a card, puts it into their hand, then shuffles
we also know that the Mega Evolution sets new expansion will feature lots of Mega Pokemon which made their debut in the Pokmon Legends: Z-A video game: also including Mega Starmie ex and Clefable though we havent seen their actual cards just yet
This happens EVERY time they draw, so if you can force your opponent to draw with something like Howling Mine, you can end the game without having to lift a finger
If you can just win off the back of some five drops then great
The release of the decklists for the Commander format comes hot on the heels of the announcement of the next set, Shadows Over Innistrad (see "New 'Magic: The Gathering' Set Announced"), due out in April
