Whenever Gylwain or another nontoken creature you control enters, choose one —
• Create a Royal Role token attached to that creature.
• Create a Sorcerer Role token attached to that creature.
• Create a Monster Role token attached to that creature.
Flood the board with nontoken creatures, stapling a +1/+1 Role aura to each one as it enters, then crash in with a swarm of buffed bodies. Gylwain turns every creature into an enchantment-matters payoff, so you pair go-wide aggression with constellation and enchantress effects to snowball card and board advantage. You can also lean voltron, dumping multiple Roles (via blink/recursion) onto one threat to swing for lethal commander damage.
Free value on every creature cast—turns even vanilla bodies into +1/+1 enchantment permanents
Strong synergy with constellation, enchantress, and aura-matters payoffs since Roles are enchantments
Flexible per-trigger choice: ward 1 protection, trample for evasion, or scry filtering
Snowballs hard with blink and recursion that re-trigger the ETB ability
Board wipes erase both your creatures and the attached Role enchantments at once
Roles only trigger off nontoken creatures, so pure token strategies whiff
Gylwain himself is a 3-mana 3-loyalty-style engine that draws removal
Each creature keeps only one Role at a time, capping per-body buffs unless you blink
