Banish 1 Tuner and up to 2 non-Tuner monsters from your Graveyard, and if you do, Special Summon 1 "Stardust" Synchro Monster from your Extra Deck whose Level equals the total Levels of those banished monsters, but it has its effects negated. (This Special Summon is treated as a Synchro Summon.)
I like this little event. It's the 3rd event I'm apart of besides the Odion, the Tag Team and the events going on now. I love how it gives free to play an option to get better cards, gems, etc. I hope they do more like this in the future.
At the bottom of the screen there's a points multiplier option, you can set that to x3 for triple points. It costs you x3 resources, but will give you loads of extra points all at once
I do like this event, being able to grind for useful but still rare rewards even after obtaining the main one is great. I don't understand why all events insist on the 30 rare jewel thing though. Would rather have nothing!
