Cards equivalent to “Wildwood Mentor” (green, with a similar effect: giving +1/+1 counters when another creature enters):

• “Cylian Escort” (similar stat boost on ETB)
• “Ridgescale Tusker” (distributes +1/+1 counters when it enters)
• “Blessed Sanctuary” (not a creature, but protects tokens and gives you more)
• “Juniper Order Ranger” (gets bigger with each other creature entering)

Reason: These cards involve +1/+1 counters or similar “creature boost” synergy in mono-green or green-white.
