I am not very experienced with the Poke'mon TCG game, but I would suggest that you don't do to much damage to your bench. I have never found attacks that hurt me to be very effective, such as Kyogres attack. If you have some way to shift the damage however, like with the old Alakazam from the first sets, then maybe you could control that damage. Like I said, I am not very experienced, so I would check with someone else before I try this in a deck.
Besides, in my old deck I didn't find Alakazam very helpful.
