I’m more saying what I think this decks needs to than what I think it necessarily currently is. A plating or Ravager can kill someone early, without the need to assemble any combo.
That’s why regular Ravager Shops has some turn 3/4 kills with much more disruption at their disposal. Tiny robots needs to be faster and more consistent with that speed.
You can always tap it to mill yourself if you hit a dead card. Run Voltaic Key / Top to get deeper than that.
The new 5 mana 3/5 expedition map creature is a shuffle effect (as well as og expedition map). Solemn Simulacrum is a shuffle too if you want to go the basic land route. Inventor’s fair is highly playable as a shuffle.
Best place to play this seems like the Karn combo decks to me, but I guess as a top end in Aggro Shops its strong too.
