Well played, then! I decided to push for Prowl with my Rubies and paid for the 2500 coin Tracks. I have the Points Red Alert bot and got the Prowl Alt from my Rubies last night. The rest of my deck is (all MTM/MEM Episode): Inferno, Eject, Nightbeat, Wheeljack, Slingshot, and Jetfire 2. For whatever reason, Hotspot didn't make my team (I used "Recommend" after placing the raid cards) and I have 2x MEM of him, nor did Ultra Magnus (higher ATK than Jetfire 2) or Silverstreak.
I'm just praying I get Prowl's bot mode with my next pull. I'm right at 100 rubies now, so I have my work cut out for me.
Edit: I can one-shot up to Dead End Lvl2, and with a good Proc of Crits I can take Dead End Lvl3. Sniping is frustrating, though, since EVERYONE is trying for those "free" rubies!
