If you already control a monster, you can use "Constellar Pollux" or "Constellar Leonis" to Summon this card from your hand, giving it slightly more flexibility than "Cyber Dragon" in a "Constellar" Deck.
This card can ease many Synchro Summons as it can change it's Level very efficiently and has no Synchro restrictions, cards like "Lightwave Tuning" and "Buten" can turn this card into a very versatile Tuner.
