Arcanis the OmnipotentHow it works & interactions with other cards

Unrivaled Card Advantage

Arcanis the Omnipotent has two distinct activated abilities. The first is a simple tap ability that lets you draw three cards. Because this does not cost mana, it is one of the most efficient draw engines in Magic. The second ability costs {2}{U}{U} and allows you to return Arcanis from the battlefield to your hand. This serves as a 'panic button' to protect him from removal spells or board wipes.

Step-by-Step Resolution

When you activate the draw ability, you tap Arcanis as a cost. The ability goes on the stack, and if it resolves, you draw three cards immediately. For the self-bounce ability, you pay four mana. Once this resolves, Arcanis moves from the battlefield to your hand. Note that according to official rulings, you can only activate this second ability while Arcanis is actually on the battlefield; you cannot use it to 'return' him from the graveyard or command zone.

Timing and Common Mistakes

A common mistake is forgetting that Arcanis is subject to summoning sickness. Unless he has Haste, you cannot tap him to draw cards the turn he enters the battlefield. Another error involves the bounce ability: players often try to use it after Arcanis has already been destroyed or exiled. You must respond to the opponent's spell while it is still on the stack to successfully save Arcanis.

When to Deploy the Wizard

Arcanis is best played when you have mana open to protect him or when the opponent is tapped out. Since he represents a massive threat through card draw, he will be a primary target for removal. Use his bounce ability strategically—sometimes it is better to return him to your hand and lose the tempo than to let him die and pay the commander tax or lose him to the graveyard.

Interaction examples

Lethal Insight

Psychosis Crawler

With Psychosis Crawler on the battlefield, you tap Arcanis the Omnipotent to draw three cards. Psychosis Crawler's triggered ability triggers three separate times. As each trigger resolves, each opponent loses 1 life, resulting in a total of 3 life lost while simultaneously increasing the Crawler's power and toughness by 3.

The Infinite Bounce Loop

Hullbreaker Horror

If you have Hullbreaker Horror on the battlefield and cast a spell, you can choose to return a nonland permanent to its owner's hand. If an opponent tries to exile your Arcanis the Omnipotent, you can respond by activating Arcanis's own ability to return him to your hand. Alternatively, casting any spell with Hullbreaker Horror out allows you to bounce Arcanis for free, saving your mana for other plays.
