chilling reign pokemon booster box Pack – Common Lands each packed with 10 cards Unboxing & review: Pokemon Chilling

The Ruby/Steel deck for Reign of Jafar feels like the latter deck in this dichotomy

Once you announce that you're activating the activated ability, no player may take actions until the ability has been paid for

Y'shtola can blink a creature on both the original end step and the extra one

At tournament and casual play levels, the most expensive cards aren't much more expensive than any other game, and people who buy booster boxes today will often have a personal reason for choosing one card game over the other

I would also suggest finding ways to be able to attach more than one energy card per turn to this Pokemon so you could use Flare Blitz every turn instead of every two turns
