Enchantment Transfusion

Rule Interactions:
 * Nullify can block the casting of it, but does not interact with the reveal effect, so you can move enchantments to a creature which has an attached nullify.
 * You can move a block immediately after the Declare Attack step in time to prevent the attack. Nullify can similarly be moved to prevent a spell.

Codex:

You may move any number of enchantments you control. X is the sum of the costs for all the enchantments moved. The Enchantment Transfusion’s when-revealed ability targets the creature the enchantments are being moved to; the Enchantment Transfusion spell itself does not. Thus, for instance, a Nullify on the creature the enchantments are being moved to will not be triggered. If a creature is being attacked, you can (for example) move a Block enchantment to that creature with Enchantment Transfusion at the end of the Declare Attack Step; the Block will then trigger during the Avoid Attack Step as normal. If a Dispel or other spell is targeting an enchantment, and that enchantment is moved with Enchantment Transfusion, the Dispel will be canceled (even if the move was to another creature in the same zone). See “Changing the Range or Target of a Spell”. The enchantments must be moved to a legal target creature (a target you could cast the enchantments on as if you were casting each enchantment again on the new target). The enchantments must be moved to a different creature (they cannot be moved to the same creature they are already on).
