Hadri, the Hypercharger

Haste
Each instant and sorcery spell in your hand has overload. The overload cost is equal to that card's
mana cost plus {2}{u}{r}. (If you choose to pay a
spell's overload cost, change its text by replacing all instances of the word 'target' with the word 'each'.)
{1}, {t}: Add {u}{r}. Spend this mana only to cast instant and/or sorcery spells.
