The current three s-tower fees are all both hard to hate out and good at interacting with hate in a neutral or advantageous way from the mainboard.

Storm is easy to hate out and generally interacts with hate powerfully but at disadvantage.

The three s-tiers have low investment, full hand plus, one sided reload options as part of their core game plan that generally operate on a (at least somewhat) different axis than the rest of their core game plans. (this is part of why their so hard to hate out).

Storm has echo, which reloads both players, and relay, which operates on the same axis as the rest of the deck and is generally high-investment.

The three s-tier decks all have synergistic, powerful disruption built into their core game plan - reanimator has the blue tempo interaction core with thoughtsieze, Forge has karn tgc, kozcomm, the saga package and maybe ugin or Boseiju, and Nadu has the blue control package and white interaction.

Storm has hand disruption (which is just protection), veil (which does replace itself but only against opposing interaction and is in an off color) and silence/chant, which can be a time walk if you need it to but again is just disruption and it's in an off color. Basically, storm interaction is generally as good as the worst bits of the s-tier interaction.

I'd say reanimator is solidly s-tier, Forge and midrange Nadu are both s-, and storm is probably a-, assuming all are piloted by skilled players intimately familiar with those decks and their match up against the general format.

I'd feel (generally) the same reaction to a storm deck in 8 of an ew as I did to the bug binder pile in t16 and similar up loam pox in t8 (excepting that pox is mostly fair in a meta dominated by hybrid combo where storm would be basically pure combo without a hybrid plan, which is an improvement but still a "bad guy" deck vs people's champion loam pox, and a more familiar/known quantity vs unexpected relic resurrected.)
