Alesha and Kaalia - Legend Rule

[Knabber]

Hey Folks!

I've been playing around a Deck featuring Alesha, Who Smiles at Death. I mainly searched for some ways to abuse her resurrection-ability and stumbled upon Kaalia of the Vast.
It would be devastating, if Alesha attacks, gets us Kaalia out of the graveyard, while she lets you put Dragonlord Atarka or an Angel of Serenety or else directly into play. Alesha -> 2/2 Flyer + something big = Value.
Of course Alesha can get you something big straight away, if you consider that Kalonian Hydra is a 0/0 in the graveyard but an 8/8 Trample if it attacks.
But here comes the Question: Kaalia of the Vast is a legendary creature. What happens, if you manage to get a second Kaalia into play with Alesha? Her active ability says: "return target creature [...] to the battlefield tapped and attacking". So, considering that Kaalia enters the battlefield attacking, her triggered ability will resolve and lets you put something into play from your hand. Then, the legendary-rule checks if there are two Kaalias around and both go to the graveyard, giving Alesha some more fuel at the next turn or even a second combat phase.
Does this work? Or will both Kaalias be vaporised right away without their abilitys to trigger?

"Tapped & Attacking" does not cause "When it attacks" abilities to trigger: http://www.mtgsalvation.com/forums/magic-fundamentals/magic-rulings/magic-rulings-archives/308167-tapped-attacking-means

The legend rule is this: http://mtgsalvation.gamepedia.com/%22Legend_rule%22 and it gets checked every time a player gets priority.

You have to chose one of the legends with the same name and bury the rest. Legend rule check is a state based action.

In short that means that even if you get a second Kaalia in the game "Tapped and Attacking", her ability will not trigger and she (or the first Kaalia, depending on which one you'll chose) will be "Buried" before applying any damage since you will have to pass priority before that (causing state based actions to get checked)

Nice thinking tho!

Legend Rule
A state-based action that causes a player who controls two or more legendary permanent with the same name to put all but one into their owners’ graveyards. See rule 704.5k.

704.5k If a player controls two or more legendary permanents with the same name, that player chooses one of them, and the rest are put into their owners’ graveyards. This is called the “legend rule.”


704. State-Based Actions

704.1. State-based actions are game actions that happen automatically whenever certain conditions (listed below) are met. State-based actions don’t use the stack.

704.1a Abilities that watch for a specified game state are triggered abilities, not state-based actions. (See rule 603, “Handling Triggered Abilities.”)

704.2. State-based actions are checked throughout the game and are not controlled by any player.

704.3. Whenever a player would get priority (see rule 116, “Timing and Priority”), the game checks for any of the listed conditions for state-based actions, then performs all applicable state-based actions simultaneously as a single event. If any state-based actions are performed as a result of a check, the check is repeated; otherwise all triggered abilities that are waiting to be put on the stack are put on the stack, then the check is repeated. Once no more state-based actions have been performed as the result of a check and no triggered abilities are waiting to be put on the stack, the appropriate player gets priority. This process also occurs during the cleanup step (see rule 514), except that if no state-based actions are performed as the result of the step’s first check and no triggered abilities are waiting to be put on the stack, then no player gets priority and the step ends.

704.4. Unlike triggered abilities, state-based actions pay no attention to what happens during the resolution of a spell or ability.
Example: A player controls a creature with the ability “This creature’s power and toughness are each equal to the number of cards in your hand” and casts a spell whose effect is “Discard your hand, then draw seven cards.” The creature will temporarily have toughness 0 in the middle of the spell’s resolution but will be back up to toughness 7 when the spell finishes resolving. Thus the creature will survive when state-based actions are checked. In contrast, an ability that triggers when the player has no cards in hand goes on the stack after the spell resolves, because its trigger event happened during resolution.

704.5k If a player controls two or more legendary permanents with the same name, that player chooses one of them, and the rest are put into their owners’ graveyards. This is called the “legend rule.”
