Taking a look at Nova Sanctuary again, I can't help but feel that it's just not right, especially the 1000 LP cost. It doesn't suit the Nova/Parshath playstyle. So, I'll make some edits:
Name: Nova Sanctuary
Trap type: Continuous
Effect: While this card is on the field, this card's name becomes "The Sanctuary in the Sky". Once per turn, you can discard one "Nova" or "Parshath" card from your hand, except "Stellarnova" cards; Special Summon one "Nova" Fairy-type monster from your deck. If you control a non-Synchro "Parshath" monster, you do not discard cards to activate this effect. You cannot Normal or Special Summon other monsters the turn you use this effect, except Fairy-type monsters.
Thoughts, guys?
