What is everyone's opinions on the new effect 'Sentinel'? The reprinted card, Wyvern Guard, Guld, has the effect:
[CONT]: Sentinel (You may only have up to four cards with "Sentinel" in a deck)
It has also been announced that this effect will also become errata for all current Perfect Guards as of December.
Speculation states that this is going to be required because of BT 10, which has images suggesting a merging of the Paladins and the Kagero/Narukami, stopping a Paladin deck from running the Perfect Guard for the Royal Paladins and Gold Paladins.
