List of changes of the upcoming patch:

1. Boosters and elemental chests will have a slight decrease in the number of cards.
2. Boosters can now contain any card, that is, even cards that are not in the collection.
3. Chest from the store, which cost 150 crystals, is now bought for gold (1500). From it can drop from rare to legendary cards.
4. Chest from the store, which cost 500 crystals, now works as a booster (always gives a choice of one mythic out of 10, can drop a new mythic).
5. Chest from the store, which costs 2000 crystals - will drop slightly fewer cards. Resources are unchanged.
6. Daily/weekly/monthly offers on the number of cards slightly increased, comparable now to boosters.
7. Colosseum now starts from League 13. (used to start at League 10).
8. The rotation of modes has become more dense - 1 day Bosses, 2 days Colosseum, without pauses (5 launches per week some mode).
9. Healing gems will be removed from the field finally, the set with a passive for healing will be updated in the next patch.
10. Passive skills of monsters in the dungeon changed (now all under the color of monsters)
11. Selection of opponents in the Tower slightly changed, on low Leagues became easier. In Leagues 1 and 0 became a little more difficult.
12. Rewards for the Colosseum decreased in number. (but Colosseum is now more frequent)
13. The number of points for Colosseum rewards has changed. The first ones became much cheaper, the final ones became more expensive. The total number of points to get all awards has increased, but almost entirely at the expense of the last 2-3 awards.
14. Cooldown on cards in the Colosseum is now 4 hours, instead of 24 hours
15. Bosses' Health/Damage balance has been corrected. The first levels became much easier, the last levels are unchanged, just from less health/damage levels increase, but come to the same values at the end.
16. Farming rewards for Bosses have been greatly reduced, but Boss launches are now more frequent.
17. New toys will give less damage, but more doubles will be given in BattlePasses (from the next BattlePasses). Old toys will be nerfed to damage (the first 5 sets those given for level increase). The rest of the old toys will remain as they were, but with increased bonus.
