The latest rulings all concern defensive effects on your Pokemon, one way or another. Here they are in time for regionals: http://pokegym.net/cpdm/current/RulingsCompendiumEX.pdb
- Ice Barrier - send Latios ex ∂ to the bench to remove the effect?
- Psychic Protector - Fastwave, etc., stops the damage reduction reduction, but what about the discard?
- Delta Reduction - the effect resides on the Pokemon that was attacked! Where does that leave 'Feint Attack' and similar attacks?
- Sidney's Stadium - can it help your poisoned Sableye?
