Marincess Cascade (CHIM-EN068) - Chaos Impact Unlimited

Banish any number of "Marincess" Link Monsters you control (until your next Standby Phase), then target 1 face-up monster on the field; it gains ATK equal to the total Link Rating of the monsters banished to activate this card x 300, until the end of this turn. If you control a Link-3 or higher "Marincess" monster, you can activate this card from your hand.
