Chaos card tier and Chaos Compendium

Q. To complete Chaos Compendium i need to run many rare cards. And, for example, at the end i need to do all TIER 10 + 10 lvl cards. For Tri it is Laughter, Sadness, Wrath, Regret and Greed. When i farm cards i can only obtain tier 10 Greed, tier 9 Regret (not 10) and so on...

Question: where or how get rare Tier 10 cards to complete Chaos Compendium?

A. You need to use the rare tier 6-9 cards and an item from the shop that boosts the card to tier 10. Then level it using the shiny material and complete the different levels up to 10. It is called chaos tier stone and it is the one that costs 10 rubies and the very last item in the chaos stone display. If you boost to level 10 one shot you will complete all the lower levels.
