Venarian Glimmer

Targeted discard with a scaling clause was the wrinkle this design chased: most blue handles knowledge, not deletion, so handing blue a Coercion that reads its target's hand first is a deliberate cross of color-pie wires. The X is what keeps it honest, because the cost is not a knob for raw efficiency so much as a ceiling on what you are allowed to take. Pay one and a single blue, see the whole hand, and your reward is limited to a one-mana spell; pay enough X to clear the curve and you have spent a real turn casting a sorcery-grade effect at instant speed. That instant timing is the actual prize buried in an otherwise clunky rate: you can leave it up, watch a player reload to a single threat, and pull the threat in their draw step or end step rather than committing blind on your own turn. The full reveal, meanwhile, turns a guessing game into surgery; you are never the Mind Rot player hoping the discard lands on something that matters. The trade is that X taxes you for the same precision blue's counterspells already provide more cleanly, which is why this style of hand attack has stayed a curiosity rather than a staple: it answers a question (proactive, color-shifted, instant-speed discard) that blue usually prefers to answer on the stack instead.
