When this Equipment enters, attach it to target creature you control.
Equipped creature gets +2/+2 and has "Whenever this creature deals combat damage to a player, draw a card for each modified creature you control." (Equipment, Auras you control, and counters are modifications.)
Equip
(19/09/2025)
A creature that is equipped is considered modified no matter who controls the Equipment that's attached to it.
(19/09/2025)
A creature with a counter on it is considered modified no matter what kind of counter it is or which player put it on that creature.
(19/09/2025)
An Aura controlled by an opponent does not cause a creature you control to be modified.
(19/09/2025)
The number of modified creatures you control is counted at the time the ability resolves, not the time that damage was dealt.
