Talk:Stallion of the Divine King, Sleipnir/@comment-5230496-20150315160136/@comment-26069426-20150331151311

Sorry to post on a two-week old comment, but I just researched this ruling and found that the following occurs in this case:

2.1 If there are monsters which can attack, choose to either attack or not attack...
 * If attacking, proceed to 2.2
 * If not attacking, proceed to 2.1.1

2.1.1 Play timing occurs. (Counter call Sleipnir)

2.1.2 Resolution check

2.1.3 If there are monsters which can attack, choose again to either attack or not to attack.
 * if attacking, proceed to 2.2
 * If not attacking, proceed to 5.1

2.2 Rest the attacking card, and choose a target.

5.1 The attack phase ends, and proceeds to the final phase.

So if you call Sleipnir during 2.1.1, prior to the Final Phase, your opponent can choose to attack Sleipnir.
