I'm not sure I agree with the idea that they're not seeing play, and if they aren't then it has more to do with the decks surrounding the cards than anything else. All the cards you listed except the Tekahn stuff are currently mainstays in tier 1 wild decks, every single one of them, even the neophytes (though maybe not the robes). If they're not working in standard, the reason has nothing to do with the cards themselves but the decks they belong in. They are flourishing in supremely effective decks in wild at least.
some cards can go to every deck; devolveing missiles, o my yogg, Robes of Protection in in aggro decks.
i get your point but i think there cards that ppl are underestimating them so much and easily improve existing archetypes
there are cards that i think are really good but do not see play.
devolving missiles: this card is actually op and i dont know why every mage deck don't run one pair of it
Wave of Apathy: this card is out of control broken; so much tempo and swing for 1 mana and some priests used to not run this, how?
Firework Elemental: this card is so good for a common card even out of elemental synergy context, the power lvl is close to Jandice
O my Yogg: 1 mana counter spell, yes. how do you not play this? from pure to everything, the card is a one mana win condition
Tekahn+ Polkelt+HoG: this is a solid archetype by itself
Robes of Protection> Cult Neophyte: the stats are ok but the effect, wow, entire board , yes all of them are immune, vulnerable to AoE or minion, nightmare for control decks / tempo rogue, or even some aggro decks.
the list can continue but what do you think, what are the cards ppl are sleeping on?
