Let's see how well the stock list pulls off its goals: Counter Blitz is all-in on Counters and does what it sets out to do well: I count 38 cards the put counters on either themselves or other cards, nearly all of these are +1/+1 counters but there's a bit of other stuff too (4 summon creatures put lore counters on themselves like Summon: Valefor)
Sail The Azurite Sea or Tipo Growing Son would be simpler, more proven ramp choices
Review Overall, the new 2-Player Starter Set is a decent option for new players to jump in without much thought
On their WeeklyMTG stream on Twitch, they showcased a bunch of new cards, as well as a great many treatments for those cards
There arent differences between packs that come from booster boxes, sleeved packs, Ilumineers Troves, gift sets, or other boxes
And, with a more focused game plan of aggressive questing, you should have a better win rate
