Generally if I am running four cheat in targets I want one that is purely for ending the game and the rest I want to buy me time, gain me value, solve problems, and/or beat specific archetypes
Most groups are fine with it if you communicate clearly and your cards are readable and consistently sleeved
This card allows you to shift it, paying to play it on top of an existing Elsa card
Getting a 5/5, 8/8, or 10/10 for 3 mana is no joke, and surprisingly easy to do as long as Daxos can get a few turns of face time on the battlefield
Vivien lets me pick Nissa here
Once you do, you put it into your hand and it behaves like any other card you've brought into the game
