I really like that poor man's
Primeval Titan! All of the M11 titans are well above the power level of where I want a six drop to be, but swapping out trample for reach makes a huge difference in letting the green ramp deck stabilize and set up for a long game, rather than just rumbling their way to victory within a few short turns. Only fetching up one land means you have to make it count.
I'm loving that Wizards is actively trying to fill the gap in Good Green Six Drops that's been around since basically the beginning of time. They don't always connect, and sometimes they're clear swings and misses, but at least they're stepping up to the plate!
