This is a modified version of a Combrei Ramp deck posted Slepher a week ago. Recently I have been playing this version with some new cards on ladder with a decent 70% win in Diamond/Masters.
The most important new card for ramp is Eternity Core. It lets the deck go off on turn 5 and drop a Telut or Marshal/Mystic and then play a power. I am only using two because drawing one is great but drawing two isn't very good at all.
Other than that it is still pretty much the same deck. Look to drop a Behemoth then a Marshal or Marshal/Mystic then Telut.
Two new cards I have been trying are Ravid who is working fairly well and can really help stabilize vs aggro and Martyr's Chains which I am probably going to cut since it is turning out to be a win more card. Neither are necessary.
