Rev, Tithe ExtractorHow it works & interactions with other cards

Mastering the Attack Phase

Rev has two distinct triggered abilities. The first triggers the moment you declare attackers, allowing you to give any target creature deathtouch. The second is a combat damage trigger that occurs when your creatures successfully strike a player. Notably, the second ability only triggers once per player dealt damage, regardless of how many creatures hit that specific player, but it rewards you with a Treasure and a face-down exile from their library.

Resolving the Tithe Step by Step

When your creatures deal combat damage to a player, Rev's ability goes on the stack. Upon resolution, you first create a Treasure token. Next, you look at the top card of that player's library and exile it face down. Because the ability grants you permission to look at and cast the card 'for as long as it remains exiled,' you retain this ability even if Rev is destroyed or leaves the battlefield later.

Timing and Restrictions

It is vital to remember that Rev allows you to 'cast' the exiled card, not 'play' it. This means you cannot play lands found this way. Additionally, you must follow all normal timing rules; if you exile a sorcery or a creature, you can only cast it during your main phase while the stack is empty. You still must pay all costs associated with the spell, though your new Treasure tokens can help cover the mana.

Common Pitfalls

If you leave the game, the cards you exiled remain face down and hidden from all other players. Furthermore, if an opponent gains control of Rev, they do not gain access to the cards you previously exiled. The permission to look at and cast those specific cards remains tied to you, the player who controlled the ability when it triggered.

Interaction examples

Ensuring a Clean Strike

Solemn Simulacrum

You declare an attack with Rev, Tithe Extractor and Solemn Simulacrum. Rev's first ability triggers, and you target Solemn Simulacrum to give it deathtouch. This makes the Golem a much more threatening attacker, as your opponent may be hesitant to block and lose their creature, increasing the likelihood that Solemn Simulacrum deals combat damage to trigger Rev's second ability.

Doubling the Extracted Wealth

Roaming Throne

With Roaming Throne on the battlefield naming 'Human' or 'Rogue', Rev's abilities will trigger an additional time. When you attack, you can grant deathtouch to two different creatures. If a creature deals combat damage to a player, Rev's second ability triggers twice, resulting in two Treasure tokens and two cards exiled from that player's library for you to cast.

Financing the Stolen Spells

Treasure

After Rev's ability resolves, you have a Treasure token and an exiled card. If you exiled a high-cost spell from your opponent, you can immediately sacrifice the Treasure to add one mana of any color toward the cost of that spell, helping you cast their best cards against them.
