Last turn
Well what this card mainly does is it can automatically win you the duel. If you and your opponent are both under 1000 lp then all cards from the field are removed except one monster on your side of the field. Then your opponent can special summon one monster onto the field and who's ever monster is higher pretty much wins or whichever one is left standing after an attack.
See this trap is not one to be thrown in any deck you want to stall and get 1000 lp and then use a monster from lon called jowegen the spiritualist which stops you and your opponent from specially summoning a monster. So your opponent won't be able to special summon a monster and then you will win. This card is hard to use because with all of the beatdowns there is a low chance you will every be left with more than one-thousand. So i would put like 3 solemn judgments and maybe always keep an imperial order out or something you can control to lower you lp's. Well anyway if this deck is used by an experienced player it can be deadly for the duel. When used by a less-experienced person it could be like getting a bye in the tourney. i give this type of deck a 3/5 but I give this card a 5/5 in a last turn deck and if it is not in last turn deck a 1/5it is really only ment for a special type of deck and with all the jinzos this card could cost you the game if you cannot use it you loose it.
