Show & Tell
When I first crossed a Blizzard with a Tessera I chose the most yellow Blizzard I had. This was in an effort to have a strong pattern contrast in the mutation compound VS. creating virtually pattern-less white corns that barely (if at all) demonstrated the Tessera pattern. Since then I have used Blizzards without any noticeable yellow, rendering virtually all white Blizzard Tesseras. Bonus Pic . . .
