At which point in time does the strongest creature need to be selected when there is a tie?
I see that the player controlling the enemy creatures chooses when you need to know... but is that done at the start of the round (or at the first time in the round when there are two highest mana cost creatures), after a friendly creature activates, after a target of the friendly creature is selected, etc.?
Can the selection change from one point in the round to another? (I go to attack Iron Golem #1 with one creature, when Golem #2 is selected... and then later in the same round I got to attack Iron Golem #2 with another creature, when Golem #1 is selected, for example.) I understand that a creature being summoned into the arena by the opponent can change which of his creatures is the strongest in the middle of a round, but other times?
This is just enemy creatures... right? I mean, if my friendly creature was the strongest in the arena, I would never be targeting the strongest in the arena....
