Fun Fact: Did you know that despite having drawn 6 of the 12 cards of your deck on turn 3, there is an 80% chance you will not have drawn Electro?
If you have not drawn Electro by turn 4, follow the standard DeathWave flowchart. Electro+Magik will allow you to play 2 cards on turn 7 (3 if Death is discounted enough) while the oppoent can only play 1.
Use the Destroy package to discount Death and build a couple of strong cards in two lanes. It is best to use Carnage or Venom to remove Electro instead of Enchantress. Yondu> Bucky> Electro> Carnage is an ideal play. Try to have at least 1 open space for Doom to place his tokens, use Carnage/Venom to clear space if needed.
T3: Electro
T4: Destroy/Enchantress Electro
T5: Magik + 1 energy
T6: Wave + 4 energy (Enchantress/Bucky+Carnage)
T7: 8 energy to spend, Death will cost 0 if 4 or more cards have been destroyed
