This is a two-cost, inkable character with one Strength and three Willpower
A 7/7 with flying and haste, Karrthuis provides all other Dragons under its owner's control with haste, meaning that once Karrthus is in play, each Dragon at its controller's disposal becomes quite aggressive
It also just provides a massive boost in mana
An extra turn might not seem that amazing considering you won't have much mana left the turn you cast this, but the real power is that it gives you the opportunity for all your other creatures and planeswalkers to provide extra value
This means that it will rarely ever be a dead card since you can always exchange it for something else
