When Phylath enters, create a 0/1 green Plant creature token for each basic land you control.
Landfall — Whenever a land you control enters, put four +1/+1 counters on target Plant you control.
Ramp into Phylath, flood the board with Plant tokens equal to your basic lands, then turn extra land drops into massive +1/+1 counter pumps. You grind value through land-based ramp and recursion, building a wide army that quickly gets tall and lethal.
Immediate board presence the turn Phylath lands, scaling with basic count
Landfall counters make Plants huge fast for go-wide or go-tall attacks
Deep synergy with land ramp, fetches, and extra land-drop effects
Green/Red gives strong recursion and ramp to recast Phylath after removal
Relies on basic lands, so fetchlands and nonbasic-heavy mana bases shrink the ETB payoff
Board wipes erase the Plant army and reset your investment
Counters concentrate on one Plant, vulnerable to spot removal
No built-in evasion or trample without support; can be chump-blocked
