Il s'agit de Lunalight Scarlet Tiger dont l'effet est le suivant (note: c'est un monstre de niveau 5)

If you activate a “Lunalight” monster’s effect (except during the Damage Step): You can Special Summon this card from your hand, then if you activated this effect during the turn your opponent activated a card or effect, you can add 1 “Polymerization” from your Deck or GY to your hand. If this card is sent to the GY by card effect: You can Special Summon 1 “Lunalight” monster from your face-up Extra Deck or GY, except a Level 5 monsters, but it cannot activate its effects. You can only use each effect of “Lunalight Scarlet Tiger” once per turn.

Surprenemment c'est le seul et unique monstre de tout l'archetype à être LV5 donc sa restriction ne limite que ça propre invocation.
