For my current list it is:
OUT: -4 Chalice, -4 Thalia, GoT, -1 Thalia, HC, -2 Containment Priest
IN: +3 STP, +2 Orzvoh Pontiff, +1 Elspeth, +2 Disenchant, +2 Stoneforge, +1 Batterskull
= 11 cards
More or less the same, which means cut mainly Chalice & Thalia 2.0 for more Removal and some Bombs.
Sometimes i leave in Containment Priest too but it will be super hard if you face Flickerwisp with your own priest on the field. Elspeth is not the strongest option here, 3rd Smasher or 3rd Palace Jailer would be better but Elspeth is a strong card against a lot of other situations (fly over moat, stalled ground etc.) that i like her as a 1off and overall she is not bad vs DnT if you can avoid Revoker.
Leyline is only really good if you really want to destroy Br Redanimator and other GY Decks - BUT you can't cast them, so you need to mulligan (which will result in mulligan away otherwise good hands with chalice/thalia) they are a very bad topdeck and you need 4 Slots! Br Redanimator will bring stuff like Wear//Tear (cause we play Chalice) and Sneak Attack/Show&Tell (non-GY-cheats) so Leyline will only save you for 1-2 turns. I would prefer Faerie Macabre here, because it blanks permanent Hate that try to answer our various permanet disruption like Chalice, Thalia, RiP etc.
Yes i lost 1:2 to Br Redanimator at my last tournament but overall the matchup isn't that bad because we have a lot of Combo Hate at Main and can cast some cc2 Hate as early as Turn 1. With 2 Containment Priest at my current Main i only run 2 RiP at Side because it should be enough in most cases and you can fight many GY tactics with a lot of other cards. Note: I don't use RiP against Shardless BUG anymore. With Priest i also have 4 cards i can use here, but Priest itself can be used against other decks (Elves, Sneak&Show, creature heavy decks etc.) and even RiP can be a solid topdeck if you start with other permission cards on your starting hand.
