The standard opening play for Ninja has 2 main focuses: Ensuring you have a way to put Jio onto the field in some way, and having reasonable access to either Ninjitsu Art of Duplication or Ninjitsu Art of Dancing Leaves
Later on, it's a 4/5 that also makes your creature lands awesome
If you add 2 'roid' monsters to your hand with 'Expressroid's' effect while you control 'Ambulanceroid', you can activate its effect to Special Summon both 'roid' monsters
With cards like Number 22: Zombiestein, Fantastical Dragon Phantazmay, and Hot Red Dragon Archfiend Abyss, Thunder Dragon can disrupt Sky Striker Mecha - Widow Anchor and any other attempts to negate Colossus
Kinetic Soldier's attack will always be 3350 when battling, The Hunter with 7 Weapons will always be 2000, and Frontier Wiseman will protect all your monsters (including itself) from being targeted by spell effects
