Sir 73, Cyber Strategist

When Sir 73, Cyber Strategist or another creature enters the battlefield, put a +1/+1 counter on that creature.

Creatures you control with +1/+1 counters have Vigilance and Lifelink

At the beginning of your end step, if you control
two or more creatures with +1/+1 counters, create a Frost Token

"Strength comes in numbers, and mine happen to be bigger than yours." - Sir 73
