“You cannot play Shiva, Lady of Frost or Card Name Ysayle while already in control of either Character.
When Shiva, Lady of Frost enters the field, choose 1 Character opponent controls. Dull it. Freeze all the Forwards opponent controls.
Put 3 Backups into the Break Zone: Remove Shiva, Lady of Frost from the game. Then, play Shiva, Lady of Frost onto the field.”
As you can see, Shiva comes in with a great ability. Dull one Character and Freeze all the Forwards opponent controls. You can even reuse it, as long as you have 3 backups available. Plus she only costs 5CP.
On a closer look. You can see that you cannot play Shiva, Lady of the Frost onto the field if you already have Ysayle out. And that is fine, we won’t get into why, but we’ll say that Shiva, is a leveled up Ysayle. As you can dull Ysayle (14-020R), put her in the Break Zone, and then play Shiva on to the field.
You already know I’ll say, Duke Larg (1-057R) for the +1K buff. Scholar (5-030C) will help you pull Ysayle out of the Break Zone, if you need to.
Now, Ysayle (6-022R) will let you search for an Ice Forward. But, since Ysayle (14-020R) is already out you might not play the other one, but this one can be put in the Break Zone to help pay for bouncing Shiva, but you might just be causing more headaches this way.
Moogle (XIV) (14-037C), is great, not just for Shiva, but any other Primal as well, depending on what elements you are playing. Same goes for Amalj’aa, Ixali, Kobold, Sylph, and Sahagin. As each one will activate whenever a Primal enters the field, and all have abilities that can only be used when a Primal is on the field.
Shiva, Lady of Frost is a great card to add to your existing decks. Or any Ice deck for the matter as long as you’re Dulling and Freezing.

On the the card.
At 2CP, this card is a no brainer. And with those abilities, she’s deadly. starting at 4K, but each Earth or Water forward gives her +2K. You can just throw her in a deck with Vikings and call it a day. Now if you control 3 other Forwards that are either Earth or Water, she’ll have 10K. And, at 10K she deals your opponent 1 point of Damage at the end of the turn. Your turn, and your opponents. The game will pretty much take care of itself if you just pass and defend Sophie. 
5CP/Lightning
Now, we’ll need to search for Behemoth K, and there’s no one better than Aldo (10-086C) who will search for a Lightning forward. Not only will Aldo let you search for Behemoth K, 
but also for Illua (5-099H). and, everybody loves Illua. And, you can’t forget about Estinien (6-088L). Behemoth K and Estinien is like having Hulk Hogan and “Macho Man” Randy Savage on a tag team. Wait, they were a tag team. The Mega Powers.
On to the Stats.
Let’s find some searchers. Epitav (6-067R) and Kolka (7-069C) will both let you search for Leo. While Luminous Puma (8-080C) will allow you to grab Leo from the Break Zone. You might as well grab Larkeicus (9-076H) to be able to grab Luminous Puma from the Break Zone or to search for him.
when Luminous Puma is put from the field into the Break Zone, you can search for a Luminous Puma and add it to your hand. You can add all sorts of Monsters. Especially ones that turn into Forwards.
