Why should the Rock be scared of cascade creatures? Don't you have access to one of the best in the format: Stoneforge Mystic? I don't understand why SFM isn't part of the core of the Rock. I played this deck exclusively a few years ago and it was glaringly obvious that SFM + Bob made this deck the go-to midrange deck. People were experimenting with more classical tempo versions using Mox Diamond and Goyfs but when it came to card advantage, SFM + Bob Rock was at the top.
Why not use all the rock-solid synergy available to this color combination instead of playing vanilla beaters like Goyf or Loxodon Smiter when you have all the tools available to out-value most midrange decks nowadays. I also fail to see how playing numerous large beaters is being maximized by the deck's strategy. As someone else mentioned earlier, BGW's color combination strength is in its removal suite as it has all the cheapest and most resilient unconditional removal. This sort of removal suite allows for smaller creatures with value effects or heavy disruption because size is not a determining factor here.
I lent my rock deck to a friend that wanted to try out legacy about 6 months ago... he Top8'd a CMT filled with Jund (13 out of 40+ players) and Shardless BUG (saw 3 in the room) decks. I know he faced Jund twice and BUG once and completely crushed through the entire tournament. Meanwhile I got completely wrecked by Jund decks all day (3 rounds in a row) while I was on Stoneblade...
The deck I lent him wasn't even refined but followed a very strict and linear strategy: Discard, Removal, Value. It simply played all the best cards for those 3 purposes without trying to be cute. It looked a little something like this:
Creatures (12)
4 Deathrite Shaman
4 Dark Confidant
4 Stoneforge Mystic
Spells (20)
4 Swords to Plowshares
2 Abrupt Decay
2 Thoughtseize
4 Inquisition of Kozilek
4 Hymn to Tourach
4 Lingering Souls
Others (7)
4 Liliana of the Veil
1 Umezawa's Jitte
1 Sword of Fire and Ice
1 Batterskull
Lands (21)
4 Wasteland
4 Marsh Flats
4 Verdant Catacombs
3 Scrubland
2 Bayou
1 Savannah
2 Swamp
1 Plains
Sideboard (15)
3 Cabal Therapy
3 Surgical Extraction
2 Abrupt Decay
2 Zealous Persecution
2 Oblivion Ring
2 Choke
1 Sword of Feast and Famine
Keep in mind that it was a long time ago and the list was a last-minute sketch stitched together with what cards we had left. We had Goyfs available but didn't feel like he consisted of any value or disruption so he was not played. KotR didn't add nearly as much value or disruption as his counterparts (Liliana and Souls) so he didn't make the cut either. Once again, raw size is irrelevant when you have the best unconditional removal available.
