Forum:Galaxy-Eyes Tachyon Dragon second attack

so if i use galaxy eyes tachyon effect and detach one overlay unit and i attack.then my opponent uses draining shield. So my tachyon dragon gains 1000 points and i attack again but my opponent activates another draining shield, can i attack again? (108.41.225.233 (talk) 00:49, April 3, 2013 (UTC))
