Infinite Combo

• Reiterate, Turnabout, and infinite mana/storm outlet (Electrodominance, prowess creature)

Remember

• A countered spell is still cast (Storm take note)
• A copy of a spell with Storm will not be copied by Storm since it was not cast
• Adventures can be cast using impulsive draw (like Dark-Dweller Oracle has)
• If your adventure creature is in exile but not from being on an adventure or from an impulsive draw effect, you cannot cast it
• A creature cast from being Suspended gains haste

To Test

• Need more reach?
