This deck is very different from the one that were winning June 2018. The core of the deck is the same but the evasion is different. Mystic Remora main deck, Night's Whisper and some strategic bounce spells.
The style of how the deck is played has also changed, idea of running out all of the artifact early has changed. I see several players playing into the explosion of a go off.
How do you beat this deck now? Energy Flux is not as good. Stony Silence is good if you have access to it, and Null Rod is not getting it done without some serious pressure.
Is it really just taxing spells now to get past the deck? What the sideboard options? They bring in Karn and power him out, he is hard to deal with.
With Eternal Weekend right around the corner discussing how to beat this deck is very relevant.
