A person at my league is under the impression Unown G stops all effects and not just your opponents, and is using G on Lugia LEGEND to do 200 a turn with no discarding. Does anyone have a reliable source I can prove to him you can't do that?
Lunar Wing said:=/ Unown G had an errata to change it from saying something like "yours and your opponent's attacks" to just "your opponent's attack". This errata can be found in the compendium.

GUARD (Unown G - Great Encounters)
Q. Does Unown G's "GUARD" Poke-POWER prevent effects from attacks that the Unown G is attached to?
A. No, the Poke-POWER only prevent effects from an opponent's attacks, not your own. Unown-G's "GUARD" Poke-POWER should say, "As long as Unown G is attached to a Pokemon, prevent all effects of attacks, excluding damage, done to that Pokemon by your opponent's Pokemon".
