Splice onto Arcane (As you cast an Arcane spell, you may reveal this card from your hand and pay its splice cost. If you do, add this card's effects to that spell.)

Destroy all artifacts you don't control, then exile the top X cards of your library, where X is the number of artifacts that were put into graveyards from the battlefield this turn. You may put a creature card exiled this way onto the battlefield. It gains haste. Return it to your hand at the beginning of the next end step.

When this creature enters, return target artifact card with mana value 3 or less from your graveyard to the battlefield. It gains haste. Sacrifice it at the beginning of the next end step.

Return all Mount and Vehicle cards from your graveyard to the battlefield. Sacrifice them at the beginning of the next end step.

Vehicles you control become artifact creatures until end of turn. Creatures you control gain haste until end of turn.

When this creature specializes, you may sacrifice another creature or an artifact. When you do, return target creature card from your graveyard to the battlefield. It gains haste. If its mana value is 4 or greater, sacrifice it at the beginning of your next end step.
