While Shudderwock may have a tiny bit more infinite value, that doesn't mean that some rather forgotten cards can't see any play whatsoever. Introducing Spirit Echo and Arch-Thief Rafaam, both of which help with playing a heckton copies of Carnival Clown. Rafaam just happens to give us a 10-Cost Spell, which, with Yogg-Saron, Master of Fate, can Corrupt Clowns. Then, on the combo turn, play Clowns, Lightning Bloom and Echo so that each dead Clown returns to hand and gives you a number of 7-Clown waves ready to overwhelm your opponent with.
