Forum:Rocket arrow express maintenance cost vs macro cosmos

If my opponent controls Macro Cosmos and I control Rocket Arrow Express, what will happen in the standby phase of my next turn? Will Rocket Arrow be destroyed since I can't send my hand to the grave or can my hand be banished instead? I'd assume it would be destroyed, but I'd like to double check. 98.206.70.2 (talk) 15:36, June 29, 2013 (UTC)
