My favorite deck strategies For me, the stars of Phantasmal Flames are Mega Charizard X ex and Mega Gengar ex, so I had a good think about the best decks I could make for them just from Phantasmal Flames and Mega Evolution cards
A 7/7 plus a Sudden Impact is often going to be game, but sometimes its just a nice way to deal with a planeswalker (or two!)
If a face-up Insect Synchro Monster(s) you control is destroyed by battle or card effect, while this card is in your GY: You can banish this card
This skill, by in large, is fine, as Alternative White is an Effect monster that can pop a monster off the field, but you might be better off using Ultimate Dragons
It knocks out foes with quick, virtually invisible punches
Decimator of the Provinces 10 Creature Eldrazi Boar 7/7 Emerge 6GGG ( You may cast this spell by sacrificing a creature and paying the emerge cost reduced by that creatures converted mana cost.) When you cast Decimator of the Provinces, creatures you control get +2/+2 and gain trample until end of turn
