Syrus Truesdale is a main character from the YuGiOh GX series. He is the brother of Zane Truesdale and similarly uses a machine themed deck. Throughout the series we can see his ranking in Duel Academy rise, as he goes from the Slifer Red dorm to Ra Yellow and finally to the Obelisk Blue Dorm, all the while remaining as one of Jaden's closest friends.
Syrus uses a Vehicroid deck, consisting of Machine-type monsters that are based on Vehicles. Although the effects of these monsters vary and there is no coherent strategy among them, they are able to support each other and fusion summon into bigger more powerful Vehicroids.
Check out My Ride! Can be used each time your Life Points decreases by 1800. In the Draw Phase, instead of doing a normal draw, draw a random "roid" monster.
Draw Sense: Earth Can be used each time your Life Points decrase by 1500. In the Draw Phase, instead of doing a normal draw, draw a random EARTH attribute monster.
Check out My Fusion! Can be used each time your Life Points decreases by 1500. Instead of doing a normal draw, "Vehicroid Connection Zone" is added to your hand from outside of your deck.
My Monster Cards If your Deck contains 6 or more Level 4 or below Monster Cards with different names, you will have improved chances of having a Level 4 Monster Card in your starting hand.
Training Wheels Can be used each time your Life Points decrease by 1000. During this turn, if a monster whose original name is "Cycroid" or "Pair Cycroid" attacked this turn, that monster will be banished until the beginning of your next turn.
Fusion Reserves - Roids Can be used each time your Life Points decrease by 1800. From your Deck, add 1 Fusion Material whose name is specially listed on a "roid" Fusion Monster card in your Extra Deck. This Skill can only be used once per Duel.
Sorry for asking what is probably a dumb question but what is his signature card for Duel Links? I wanted to see the animation for the summon but I was distracted when I unlocked him. I never saw which card is his signature and it is not written in his biography.
I have summoned all kinds of roid monsters with him but have yet to find his signature card.
As someone only interested in Zombies and Roids, I am sad. Honestly tho I'm fairly content with Syrus's. 3 Connecton Zones and a Truckroid as well as drastically eased burden of farming drops since he doesn't appear at the gate.
