Special Summons from your Graveyard / Cannot Special Summon
Not that impressed with this card. All the best Blackwing Synchros are level 7 so you really need a level 3 tuner instead combined with one of the level 4 none tuner monsters(that can be special summoned)
Don't invest in the deck yet unless we see some worthwhile cards (blizzard is not enough as we need some good extra deck option). Blackwings could easily be top tier but we can only say as much of the deck gets the cards that it may need.
