Decklist

Main list for Rosinante OP12.

Options & Tech Cards

Flexible slots to adapt the list.

The deck allows few changes and in my opinion these are the best. Law allows you to maximize the searches while the spells are situational and depend a lot on how the meta is set. Gamma Knife helps against Kid Fortress, and the unblockable one is a small tech card that can help you steal some games. You can insert them by reducing some 2K.

Mulligan

One of your searcher for missing curve + promo Law for ramp and establishing your board.

If you do not see this combo, mulligan is the way.

Curve Guide

Turn-by-turn curve reminders.

Curve

1/2 DON

Search for missing character.

3/4 DON

Promo Law is the best choice because it allows you to play in the curve without going negative of DON. Law blocker instead is a valid option for a tempo play against decks like Ace.

5/6 DON

Vergo is essential against blue deck or based removal. Your choice is always the new Rosinante to start growing your board and putting pressure.

7/8 DON

Law 7C allows you to bring the Leader to 6k base and make your blockers even more problematic for the opponent. Against decks like ST29 or Boa, the new Law 6C allows you to push and heal yourself so as to ruin their plans.

Late game

This card allows you not only to counter, but also to take a Law from the trash so you can use a 2K against a 5k base attack. Use it carefully to resume Laws like 8c, but remember you only have 4x.

Tips

Key reminders and timing notes.

Leader ability allows you to play in any curve, so choose the most annoying one for the opponent and force them to play by your rules. Saving all your board from KO does not always work against removal like Red Roc, so be careful.

Vergo is indispensable to save your Doffy family pieces, but not all are needed. That is why we only play 3x. The card is strong but is not searchable by Sugar, so think well which searcher to play in order to not mix any character in curve.

As we have seen this spell allows you to make absurd ticks and we would like to play another 4x but you can't. Sometimes it's better to let go of a piece of your board and play it the next turn, even if we don't have a play for the next round it can be useful.
