Giaganticastle is still needed in blue eyes deck for it's atk Power against ancient gear reactor+geartown+castle u need spirit end phase can't banish stone if u don't get lethal ofcourse this card will be in Blue eyes deck
Oh no boy.. u got a reactor and a gear town u got second u think destroying reactor with this and swinging in With this for 3k will be good by banishing ancient stone?syncro summon castle with spirit and ancient take out reactor summon another Spirit to take out both castle and geartown..
If you're summoning a lvl9 against ag with spirit and can't go lethal with this then giaganticastle with spirit taking out their castle is optimal play but ofcourse this is a must play card in blue eyes
