Eight-and-a-Half-Tails AvatarHow it works & interactions with other cards

Understanding the Protective Roll

The ability costs one generic mana and targets a permanent you control. Upon activation, you must identify all colors that the target permanent does not currently have protection from. The game then chooses one of those colors at random, and the permanent gains protection from that color until the end of the turn. This means it cannot be damaged, enchanted/equipped, blocked, or targeted by anything of that specific color.

Step-by-Step Resolution

First, activate the ability by paying one mana and selecting a legal target permanent you control. When the ability resolves, check the permanent's current protections. If the permanent has no protection, you choose randomly between White, Blue, Black, Red, and Green. If it already has protection from Red, you choose randomly from the remaining four. Once the color is determined, the protection effect is applied immediately and lasts until the cleanup step of the current turn.

Common Mistakes and Randomness

A common error is trying to activate the ability after a spell has already resolved; you must use this in response to a spell or ability while it is still on the stack. Additionally, you cannot gain protection from a color the permanent already has protection from. If a permanent somehow gains protection from all five colors, the ability will have no valid colors to choose from and will fail to grant an additional effect, though the ability itself can still be activated as long as the permanent is a legal target.

Strategy: When to Activate

Because the color is chosen at random, this ability is best used when your opponent relies on a single color for their removal or when you have enough mana to activate it multiple times. If your opponent targets your creature with a Black destruction spell, and you randomly get protection from Blue, you may need to activate the ability again to try and hit Black. It is also an excellent tool during the declare blockers step to make a creature unblockable by a specific color of defender.

Interaction examples

Shielding Your Mana Source

Sol Ring

If an opponent attempts to destroy your Sol Ring with a targeted artifact removal spell, you can spend one mana from Command Tower to activate Eight-and-a-Half-Tails Avatar targeting the Sol Ring. On resolution, if you randomly roll the color of the opponent's spell, the Sol Ring gains protection from that color, causing the opponent's spell to fizzle because its target is now illegal.

Generating Mana for Protection

Command TowerSol Ring

You can tap Sol Ring to add two colorless mana, allowing you to activate the Eight-and-a-Half-Tails Avatar ability twice in a single turn. This is particularly useful if your first activation results in a color that doesn't help you in the current combat phase, giving you a second chance to roll for a more relevant color like the color of an opponent's blocking creature.
