Hah, and I don't even play meta magic. Best way to get rid of decks like that are as follows (in my opinion and from experience);
1) MATCH their creature output with token producers or dropping low drops as well.
2) Going after the player with direct damage. Hold off their creatures but focus on the PLAYER.
3) Rip their decks apart (not literally) but using mill, card discarding and wide scale burn damage that does not target. This can also be done by -x/-x creatures on the board (this works best if creatures are indestructible).
Your thoughts on this?
