Creatures you control with +1/+1 counters on them have trample.
, : Create a 0/0 green and blue Fractal creature token. Put X +1/+1 counters on it, where X is the number of differently named lands you control.
Emil is a mono-green +1/+1 counters and lands-matter commander who turns a diverse land base into a giant trampling Fractal each turn. You ramp aggressively while playing differently named lands, then activate Emil to make repeatable, snowballing tokens that all have trample thanks to his static ability. Pivot into a counters/+1/+1 matters payoff package to overwhelm the table with huge bodies.
Repeatable token generation that scales with a varied land base, giving inevitability
Mono-green excels at ramp, land tutors, and Fractal-sizing landfall synergies
Static trample ability makes all your counter-creatures hard to chump-block
Resilient gameplan that doesn't rely on a single combo to win
Activation costs plus a tap, so it's mana-hungry and slow without ramp
Vulnerable to board wipes that erase your invested counters and tokens
Mono-green struggles with interaction, lacking counterspells and removal flexibility
Wants many differently named lands, which can conflict with efficient land tutoring of duplicates
