Fate egg SoR is still viable. 4 creatures for 2 cards seems too good to me.
Yes, it is still viable but much like instosis, it took a major hit when SoR became a time card.
Before, it was easy to power it off of time mark and QP, and just one or 2 novas could power most of the deck's SoR quanta needs.
Now time pillars are needed in order to keep up with the demand.
Fate Egg - SoR - SoSe was one of my favorite strategies before the change over... It just doesn't have the same punch any more though.
4 creatures for 2 cards and 6
seems huge, but remember that these 4 creatures could be anything from skeletons to dragons.
Also note that you would still have to get this card out first, so it would take a turn or two to get rolling and could be disrupted by PC unless you save up and play it as a 3 card combo...
At which point you have 4 creatures for 3 cards and 5-6
+ 5-6
The big key there is that it requires a duo, since this is not a
card, so its more tricky in terms of quanta balance.
I think thats a fair trade off myself.
Instosis, on the other hand, is already guaranteed to have
production present in order to power mitosis, so this card is easier to integrate into that strategy.
