What Happens If My Opponent and I Have the Same Planeswalker
I also run ramp spells like Three Visits (thank god for reprints), Nature's Lore, Skyshroud Claim, Smothering Tithe, The Great Henge (which costs only two mana when Sliver Overlord, Sliver Legion, Sliver Queen, or The First Sliver are out), and 'rocks' like Mana Crypt, Sol Ring, Arcane Signet, and Chromatic Lantern which can't help cast the Sliver lords, but CAN help cast Morophon, the Boundless or pay for Sliver Overlord's tutor
And you will want a handful of pirates because other cards like Wendy Darling Courageous Captain, Kakamora Pirate Pitcher, and Skull Rock- Isolated Fortress gain or grant bonuses when the pirate cards are in play
In Modern I think the RG Prowess deck is slightly behind the URx version (mostly because theres no such a card as Preordain)
I like to play board states instead of having tutors as combo pieces, and the cheap suspend cost of Profane Tutor means that I can let things play out for a while before coming up with a plan
This low price was only available until late April, long before the sets debut, which started to reveal spoilers
