Best SR Speed Decks

In Marvel War of Heroes in each alignment there is always a best deck for each rarity. Of course while certain realms excel in different areas at any given moment, as new cards release the meta shifts. Inevitably all decks shift and change.

Best SR Speed Deck - Defense:

1st Card: Shapeshift Assassin Mystique - 7440 Def - Remarkably intensify DEF of Speed Cards.
2nd Card: Shapeshift Assassin Mystique - 7440 Def - Remarkably intensify DEF of Speed Cards.
3rd Card: Centurion Nova-Prime Nova - 8228 Def - Remarkably intensify ATK/DEF of Speed Cards
4th Card: Centurion Nova-Prime Nova - 8228 Def - Remarkably intensify ATK/DEF of Speed Cards
5th Card: Centurion Nova-Prime Nova - 8228 Def - Remarkably intensify ATK/DEF of Speed Cards

Mystique is the only speed card holding the defense boost for pure speed, but her defensive stat is a bit low. Because of that I prefer to stack three Prime Novas instead of the normal two for wings. His buff is effective and his defensive stats are more solid than other speed cards at the SR level. It's also acceptable to stack five Novas.

Best SR Speed Deck - Attack:

1st Card: Fire Blast Human Torch - 7793 Atk - Remarkably intensify ATK of your Speed Cards.
2nd Card: November Foxtrot Nick Fury - 8372 Atk - Remarkably intensify ATK of all your Cards.
3rd Card: November Foxtrot Nick Fury - 8372 Atk - Remarkably intensify ATK of all your Cards.
4th Card: Vampire Hunter Blade - 8840 Atk - Remarkably intensify ATK of this Card.
5th Card: Vampire Hunter Blade - 8840 Atk - Remarkably intensify ATK of this Card.

This Marvel War of Heroes deck was a bit trickier. Honestly I have reserves about using event cards like Nick Fury in builds, but I see plenty of him floating about. An alternative to this deck would be to use two Torches and two Blades. Blades stats are too high to ignore pushing closing to 9k atk. Although his buff is self, it is a significant boost as well.

Overall:
Defensively the SR Speed cards are weak. Reasonably a player could also grab three Nova, two Mystique, and two Blade, and use three Nova on attack and defense for solid stats in both.
