Overview
Yes. You may activate High Perfect Morcant’s activated ability ("Tap three untapped Elves you control: Proliferate") and tap Elf tokens that have summoning sickness to pay that cost. Summoning sickness prevents a creature from attacking or activating abilities that have the tap or untap symbol in their activation cost , but it does not stop a creature from being tapped to pay a cost for a different object’s ability. Proliferate’s operation is described in , and you aren’t required to choose any permanents or players when you proliferate .
Step 1
Confirm Morcant is on the battlefield; its activated ability is an ability of a permanent and functions while it’s on the battlefield .
Step 2
Announce you are activating “Tap three untapped Elves you control: Proliferate.” Tapping the three Elves is part of the activation cost; you must be able to pay that cost when you activate the ability.
Step 3
Select three untapped Elves you control to tap as the cost. Those Elves may have summoning sickness; the rule in prevents a creature from activating its own abilities that include the tap or untap symbol, but it does not prevent that creature from being tapped as a cost for another object’s ability.
Step 4
Tap the three chosen Elves to pay the cost, then put Morcant’s ability on the stack. After it resolves, perform the Proliferate action per . When choosing permanents/players to receive an additional counter, you may choose any number (including zero) as clarified in .
Resolution
High Perfect Morcant can be activated even if it or the Elf tokens being tapped have summoning sickness, because the restriction in only prevents creatures from activating abilities that themselves contain the tap or untap symbol. Morcant’s ability does not require Morcant to tap; its cost is tapping other Elves, and a creature with summoning sickness may be tapped as part of another ability’s cost. The effect you get is Proliferate (see ); when proliferating you choose which permanents/players with counters get another counter, and you don’t have to choose any if you don’t want to .
