The last gatherer ruling on the card {safe haven} is confusing me. Basically, when a group of creatures are entering the battlefield from the same effect, can't you normally choose the order that the creatures enter instead of entering simultaneously. When I play edh, there are often mass blink or shuffle and return effects, but as far as I know, the player was always able to choose the order that the creatures entered the battlefield. Other, similarly worded cards are linked in the discussion, like {synod sanctum}, have almost the exact same wording and effect, but have no such ruling. is this just a super special card that acts outside the normal rules?
The difference in Gatherer rulings is likely due to one main difference. The Haven says "owners control" and the sanctum says "your control." Because of this, the rulings have to specify about what happens if you controlled a creature but didn't own it, and what would happen if creatures are being put on either side of the field with the effect. It seems like a small detail, but it can cause a bit of confusion.
And as for the simultaneous thing, the creatures can enter the battlefield at the same time. However, any triggers that will go off due to them entering will be set off seperately, and in the order of their controller's choosing.
My by no means informed opinion of why safe haven has rulings that other cards don't is that safe haven is an older card, so the question came up when safe haven was new, but the ruling was already there when the other card came along. Creatures enter the battlefield simultaneously for all similar effects.
