Game BUG AFTER (2.0.02-SNAPSHOT-01.25): Battle interface slows down when playing with slivers decks.

**Describe the bug**
Greetings,
After I upgraded from the snapshot version 2.0.02-SNAPSHOT-01.25, to both the current **2.0.02-SNAPSHOT-01.30** and the previous one (i think it was the 2.0.02-SNAPSHOT-01.28), i noticed that whenever i was playing in the adventure mode with my **sliver** deck, **the game interface starts slowing down and lagging a lot for all effects, not just for the AI thinking and its reactions**. The slowdown increases noticeably in proportion to the amount of different slivers effect in play at the time, until it takes almost 30-40 seconds to resolve an effect, or even 10-12 seconds to draw a card during the draw phase.
**The interface also flickers continuously, like it was continuously refreshing and re-applying modifiers.**

**To Reproduce**
Steps to reproduce the behavior:
1. Play any match with a **Sliver** deck, whether in adventure mode or not. Easiest way to reproduce I've found is to play with a preconstructed deck called "Slivers Evolution".
2. Effects should be very noticeable after you put down the 5th or 6th different sliver.

**Expected behavior**
The battle interface should work seamlessly and without slowdowns as it did in versions up to 2.0.02-SNAPSHOT-01.25, where this issue did not happen.
