Skithiryx can also regenerate for , meaning its at least somewhat protected from removal
Kindred Discovery Drawing cards is good, but paying 5 mana for a do-nothing enchantment isnt ideal
Good equipment also helps aggro decks go the distance, since even when one threat dies, the next weenie can pick up its pile of swords and keep the pressure on
