ways to counter Geartown/reactor dragon combo: -Cosmic/galaxy cyclones: cosmmic is the safest as galaxy cyclone may hit a fortress but if you hit a double cyclone with galaxy, your opponent's geartown will miss timing if he/she chain double cyclone to destroy the card and next turn you can destroy ancient gear castle, these cards are also great against buster blader, heros and karakuri but not so much against koa'ki. -dust tornado: chain it to the initial activation of geartown or use its second effect to set a card from hand and Geartown will miss timing. -Spellbooks+ Silent swordsman: to avoid early activation of double cyclone or any other backrow remover set the first monster rather than summoning it, unless your opponent is setting his toggle to on he/she will not respond to your set. -If you are running backrows better use chainable backrows+ floodgates. -cards like magic defector, acid rain and system shutdown are only good against certain decks, great cards in tournaments. -sometimes it's better not to set a trap/spell especially if you go 2nd and you only have 1 trap/spell, double cyclone is a thread here. -Spells and traps can't be chained to reactor Dragon's Destruction effect. -AG players usually don't run strong backrows (except TTH) so it's usually safe to swing. -As a koa'ki player: summon wall instead of sandman, use maximus to destroy the castle or any monster, if you don't feel a delay expect a facedown fortress(most likely), WOD or drowning. -always try to figure out how to make geartown miss timing, fortess doesn't miss timing!
