I think that  is much more useful. Eternity and Rewind force the enemy to play card again and that leads to 1 more poison point. Unstoppable ignore shield effect and give scorpions possibility to attack and infect the enemy.Turltle Shield really help in this deck because poison is accelerating in 3-4 turn.

Crusader take skill from Jade Staff. Sanctuary heals you and protect your mana pool. Flying Weapon is for Jade Staff and you can play other Jade Staff and you have +5 heal points.

I don't think either of these decks are relatively new.
For the first, I always, always prefer two weapon so maybe,  - Rewind + Eternity or - 2 Rewinds +1 tower and Eternity
For the second, usually this is paired w/ adrenaline instead of Sancs, but I suppose they work too, lots of healing.
Definitely remove the Jade Shield. Watch if the AW suck up Life quanta.
