原文If another effect (or effects) modifies how much damage Wolverine would deal—by preventing some of it, for example—the player being dealt damage or the controller of the permanent being dealt damage chooses the order in which any such effects (including Wolverine's) apply. If all of the damage is prevented, Wolverine's effect no longer applies.
原文If damage dealt by Wolverine is being divided or assigned among multiple permanents and/or players, that damage is divided or assigned before doubling. For example, say Wolverine has three +1/+1 counters on him, making him a 5/5, and he's enchanted with Messenger's Speed (an Aura with enchant creature and "Enchanted creature has trample and haste.") Then you attack with Wolverine, and he's blocked by a 2/2 creature. You can assign 2 damage to the blocker and 3 damage to the defending player. Those amounts are then doubled to 4 and 6, respectively.
