I've been trying to find the best shell for Tavrod and Warhelm since I got the new cards and this is the version that has performed the best for me. Navani and Daisho constantly underperformed in previous versions. Rise and Sword of the Sky King have been great. There are 12 minotaurs and 12 weapons so Tavrod has an 86% chance to draw at least 1 card and about 35% chance to draw 2 cards. If you draw Warhelm but not Tavrod, you can either play Warhelm on Interrogator or Rise for a Tavrod.
