The Illumineers Quest: Deep Trouble box will feature two pre-built decks players will be able to use to fight back against Ursula, with the decks featuring cards from across all sets released for Lorcana and will contain a new Mulan, Gifted Archer card and a Yen Sid - the wizard from Fantasia - card

As for Atarka she maybe a little too powerful in dragon deck maybe make focus on creature with power four or greater since temur like those (a minor improvement since like 97% of dragons are 4 or higher) and instead of counters make it a firebreathing effect?, instead of just creatures maybe something like this "Whenever you draw a card dragons you control gain +1/+0 until the end of the turn" "Whenever a creature with power four or greater enters the battlefield under your control draw a card than discard a card, if this creature was cast from your hand instead Scry 1 and Draw a card" this way if you cheat a monster onto the field you still get the draw but you have to discard, but if you cast it from your hand it rewards you with more utility (you have blue use more of it)
Caretakers TalentCaretakers Talent, from the main Bloomburrow set, gives us card draw when we make tokens
These packs are more expensive, but are much more likely to include various foil treatments, extended arts, and all sorts
Thats good and it will mean more availability in stores, and less on the secondary market going forward
The Secret Lair Drop Series is best described as a supplementary set for Magic: the Gathering that offers new variants of existing cards or brand new, non-canon cards to help promote a tie-in or event
