Ambush Commander and Dual Lands

[Tempe]

Will an [card]Ambush Commander[/card] turn a [card]Tropical Island[/card] into a 1/1 Elf? If so, does it have summoning sickness? If so, does that mean it can no longer tap for mana the first turn it comes into play as well? Thanks in advance.

Yes, yes, and yes. In that order.

The land will only have summoning sickness if it came into play that turn.  Lands that have been in play long enough will not have it when you play the Ambush Commander.

Question 1: Will an [card]Ambush Commander[/card] turn a [card]Tropical Island[/card] into a 1/1 Elf?

Answer: Yes, just as a polluted delta can go get a volcanic island, Ambush Commander makes Tropical Island an elf.

Question 2: If so, does it have summoning sickness?

Answer: If you played it the same turn that you played the ambush commander, then when the Tropical Island becomes an elf, it will have summoning sickness and be unable to tap. If you played it during a prior turn, it will not have summoning sickness.

Question 3: If so, does that mean it can no longer tap for mana the first turn it comes into play as well?

Answer: After the Ambush Commander resolves making the recently played tropical island a 1/1 elf with summoning sickness, it can no longer be tapped for mana until the following turn when it is no longer summoning sick.

Question 2: If so, does it have summoning sickness?

Answer: If you played it the same turn that you played the ambush commander, then when the Tropical Island becomes an elf, it will have summoning sickness and be unable to tap. If you played it during a prior turn, it will not have summoning sickness.

Summoning sickness is "healed" at the beginning of the controllers first upkeep after the permanent comes under his/her control. So suppose player A plays a tropical island during his turn, then passes the turn to player B. During player B's turn, player A activates winding canyons and pops the ambush commander into play, then the tropical island played the previous turn will still have summoning sickness, since player A hasnt had an upkeep of his/her own yet.

Permanents that are confiscated/donated by players will also have summoning sickness untill the new controllers first upkeep. So no stealing of dreadnoughts during your turn and immediately using it to smack its previous controller for 12 (well, unless you are a s4v4g3 cheator).
