I think we can all agree that MLP Tales' Melody (top left) Starlight (top right), Clover (bottom left) and Sweetheart (bottom right) are allies. The card's info says:
Pony Allies
Continuous Spell
During each of your Standby Phases, put 1 Ally Counter on this card. If a "My Little Pony" monster you control is selected as an attack target, you can remove 1 Ally Counter from this card to negate the attack.
