Magical Prison and Trading Places

These cards are awesome, since they bypassed any protection, including Lifeforce, since the cards technically never leaves the field. Not to mention they clogs the opponent's backrow with a useless units. should see more play imo.

I agree, very useful as generic monster removal as well as in things like Frozone. Maybe their increased use will warrant less use of Lifeforce Shield.

Trading places also works as a pseudo MST, which is awesome.
