Bloodthorn FlailHow it works & interactions with other cards

What It Does

Bloodthorn Flail provides the equipped creature with a +2/+1 stat bonus. The most notable feature of this card is its Equip ability, which presents a choice. You can either pay three generic mana to attach it to a creature, or you can choose to discard a card from your hand as the cost instead.

How It Resolves Step by Step

First, you must have the Flail on the battlefield and a legal creature to target. When you activate the Equip ability, you choose which cost to pay: {3} or discarding a card. This cost is paid immediately as you put the ability on the stack. Once the ability resolves, the Flail becomes attached to the targeted creature. If the creature becomes an illegal target before the ability resolves, the Flail stays where it was.

Common Mistakes

One common error is forgetting that Equip abilities can only be activated at sorcery speed, meaning during your main phase when the stack is empty. Additionally, remember that you cannot discard a card to pay the cost if your hand is empty; you must actually have a card to discard to choose that alternative cost.

When to Play It

Bloodthorn Flail is excellent in aggressive decks that need to push through damage early. It is also highly effective in decks that benefit from having cards in the graveyard, such as those with Reanimate or Madness mechanics, as it turns your equipment cost into a setup for future plays.

Interaction examples

Mana Acceleration for Equipment

Sol Ring

If you have a Sol Ring on the battlefield, you can tap it to add two colorless mana. This covers two-thirds of the mana cost required for the standard Equip ability of Bloodthorn Flail, allowing you to buff a creature very early in the game without losing card advantage from your hand.

Fixing Mana for Equipment

Arcane Signet

If you are short on black mana but need to cast Bloodthorn Flail, you can use Arcane Signet to produce the necessary black mana. Once the Flail is on the battlefield, you can then decide whether to use the Signet's mana to help pay the {3} Equip cost or simply discard a card to save your mana for other spells.
