(This comment is part of Option II - Phase 1 Time Trial)
Without doubt one of my favorites Time cards in crucible.
As I saw during masters battles in these trials, in my opinion Time is missing some good cards; a mono-time deck without Devonian/Silurian Dragon for example has little chances vs other element, expecially those with good CC.
This is because one of best Time card, Dune Scorpion, is useless in a mono-time deck, and other time creature are either too weak (like déjà vu) or too expensive (like pharaoh); with this card we can use Dune Scorpions in a mono-time deck at last!
Clearly inspired by darkness card Nightfall/Eclipse, this card is balanced as cost, and it’s based, rather strengthens the already proven time-aether synergy. A time/aether duo deck with dune scorpions, Anubis and this one, for example, could be really a hard deck to counter.
I like really much that bonuses are not stackable, this would have made this card heavily OP; and I found it very clever how it was resolved (avoided) the question of a possible use (or better…abuse) of a fractal Spark/Ball Lightning.
For those who fear a fractal dune scorpions + this card, I remember two things: permafrost and jade shield.
In conclusion, I sincerely hope that one day we can all find this card in the game, which no doubt would be a great improvement for the Time element.
