the ones that come in a later version of yugioh on gameboy
they are not affected by magic or traps even ones that don't design a target
they all cost 3 sacrifices
they all have side effects
it's specal effect is that it's attack is a thousand times however many cards u have in ur hand (eg: if u have 6 cards in ur hand his attack is 6000)also if ur opponet summons a monster then it isdone 2000 dame imedialy
it's special effect is if u sacrifice 2monsters on the field then destroy all other monsters on the field and it's attack cannot be stopped
this is my personal favorite(Jack). in a proficy you destroy all monstors and all ur life points become his attack Note: in real duel monsters in japan if u revive a mon u can't attack in the same turn. he bypasses this rule
