You get lots of control over which sagas go away and which abilities you repeat
So, lets look at the best of them
In order to ensure that you simply cannot repetitively keep casting the same spells from the GY over and over, spells casted through The Eighth Doctors reanimation ability must be exiled when they hit the GY
You don't have to cast a plotted card if you don't want to (that's to say, it may remain in exile indefinitely if you want), but if you do cast it then you have to cast it for 0 in other words, alternative doesn't mean optional in this case
Get ahead on the damage-switching shenanigans if you can, and follow that up for the 210 swing if you can make it happen before Garbotoxin kicks in and gets rid of Abilities
At the time of writing its still pretty fresh off the presses, so I havent seen it in action much, but I have to imagine Sol Ring #2 for activated ability decks is something to pay attention to
