Very effective when used in a Statue control deck. Instantly gives you Guardian Statue as a +1, when your life points are lowered by 1800. Use with Mirror Wall in your deck and pay the 2000 LP maintenance to use this effect immedaitely.
Rating and explanation
This skill will probably not be used in most PVP decks. However, if your planning to build decks that revolves around summoning Gate Guardian then you might give it a try.
