Subject: Great tip to destroy any monster First, you need castle of d i, then you need a shadow ghoul, and at least 29 monsters, that shadow sword thingy and reinforcments, first let about 25 monsters die,(risky, but will help) then play shadow ghoul to bring its attack up 2 3500 then with the shadow sword it will be 3900 then with castle of dark i it will be 4100 and with reinforcments it will be 4600 high enough to destroy even the BLUE EYES ULTIMATE DRAGON!!!!!!!!!!!!!!!!!!
