How to Get
Normal summonable beater that boosts his attack to 2300 while he is attacking.
Attack is decreased by 500 when being attacked.
The best way to boost Steamroid’s attack is to counteract his debuff effect. You can use Reverse Trap to turn the 500 attack debuff into an attack boost. You can use Fobidden Chalice while Steamroid is being attacked to negate his debuff effect and give him an additional 400 attack. You can also use more simple attack boost cards to protect your Steamroid.
Since your Steamroid is vulnerable during your opponent’s battle phase, you can debuff your opponent so that they are at an even lower attack than Steamroid causing their monster to be destroyed. Battle position changing is also another way you can protect Steamroid.
