The Plus One Seasonal Event Scoia'tael deck that previously forced CD Projekt Red to end the event 3 weeks early - yes, it's that good. The focus is to create many copies of Idarran of Ulivo, then use him to create many copies of Snowdrop, which will give you 250+ points in two turns.

Mulligan Phase: You want Idarran, Snowdrop, and Decoy in your hand. It's okay to use Royal Decree or Oneiromancy to get one of those cards, but save your tutor cards if you can. You will want Renew, Malena, and one of the tutors in Round 2, so if you can get them now, they will help you in the future.

Round 1: On turn one, play Idarran, then use your leader ability to move three copies of him into the other row (technically, it is best to move any of the 1-power versions that have the Doomed status). On Turn 2, play Snowdrop and have all of her copies use their order ability. When using the order abilities, try to keep Oneiromancy, Renew, Malena, and Royal Decree in your hand, if possible. Those are the cards that you'll need in Round 2, so any other good cards are nice to have, but not necessary.

It takes a long time to use all of the orders, so do as many as you can before your turn timer runs out. If your turn timer is about to end, then save your remaining orders for your next turn. You do not want to risk ending your turn in the middle of choosing a card, otherwise the game will randomly choose for you, which could put one of the cards that you need back in your deck.

On your third turn, use Decoy on the 1-power Idarran that does not have the doomed status - it should be directly to the right of the first Idarran that you played. This will put Idarran back in your deck so that you can use him in Round 2. Pass on your next turn, and your opponent will either pass as well, giving you a quick Round 1 win, or they will need to play most of their cards to catch up, giving you huge card advantage.

Round 2: On your first turn, play Malena. On your second turn, play Idarran in whichever row is empty, then use the Malenas to move two Idarrans into the row that is not full. On your third turn, use the Malenas to move two more Idarrans into the row that has fewer units, then use Renew to play Snowdrop from your graveyard and use all of the Snowdrops' order abilities (just like you did in Round 1). If you won in Round 1, pass now and force your opponent to try to catch up to you.

Backup Plan(s): If your combos get disrupted, or the game goes to Round 3, then play like you are using a typical movement deck - use Dol Blathana Sentries in the ranged row to boost Cat Witchers, Dryad Matrons, and Gezras whenever they move. You have Yrden and Morenn to reset or lock anything strong that your opponent has. If you do not have Snowdrop, other good cards to create lots of copies of are Gezras, Ciri: Dash, and the Cat Witchers.

Alternative Options: Switch Ciri: Dash for Alzur's Double Cross to give yourself another tutor to summon Idarran, increasing your consistency. You will also save two provisions in the process, so you could then upgrade one of the non-essential cards into something else.

Warning: People may hate you for using this deck. They may not give you a GG at the end of the match (given how game-breaking this deck is, I cannot really blame them).
