If you aren't too attached to the doubling feature, the card would still be nice just adding the stats across.
EA would function like a more predictable but slower Chaos Power. Guaranteed +4|+5 but having to wait a turn to use it doesn't sound horrible. It's a lot more expensive, but it doesn't require a monster in order to use the card. Plus, the turn you're waiting to use the ability, the card is still doing the damage it would have otherwise done when added to another card.
