Forum:Evil Hero Dark Gaia Question

Ok, so in order to summon Dark Gaia, are there any restrictions on the cards you can tribute/remove from play? Also, can you tribute/remove from play dark gaia? If so, does the new dark gaia get the attack that the old dark gaia had while on the field or does it get 0 attack? 70.253.164.115 (talk) 02:42, March 31, 2011 (UTC)
