Master of Lightning and Tempo
This guide is for players with a basic understanding of the hero. For a full introduction, check out the official tutorial.
As one of Classic Constructed's most sophisticated tempo decks, [object Object] is fundamentally a pure tempo deck that happens to combo - not a combo deck with tempo elements. This distinction is crucial to understanding optimal play patterns and strategic decision-making.
Oscilio succeeds through consistent value generation rather than all-in combo attempts. The lightning tag serves multiple strategic purposes beyond simple damage output.
Lightning spells excel because they are instant speed, block for 3, and are cyclable through sigils. Most importantly, arcane damage attacks your opponent's resources directly - when you send arcane damage, opponents must use blue cards and equipment to mitigate, stripping away their best cards and disrupting their game plan.
Arcane vs Physical: When opponents block physical attacks, they use their worst cards and keep their best. When they face arcane damage, they're forced to use premium resources, fundamentally different value exchanges that favor the Oscilio player.
Lightning Greaves serves as your primary hand unlocker. Even with suboptimal hands, activating Greaves can generate 12+ value by converting blocked cards into offensive pressure. Aether Bindings enables surge plays that transform the entire game state, while Volzar provides consistent utility and combo enablement.
Every Oscilio decision revolves around maximizing card value through the Hamilton system:
Block 9 (three cards blocking for 3 each), play Loading... (assume 4 value off draw) = 13 total value from 4 cards while allowing for explosive hand scaling.
The most critical Oscilio skill is proper arsenal management. Always arsenal Loading... when possible - this is your perfect game plan setup piece.
Never sacrifice Gone in a Flash for random card draw unless you haven't seen it in many turns.
Understanding which cards enable the tempo engine versus providing raw combo potential separates skilled Oscilio pilots from button mashers.
Gone in a Flash is your "unlock the hand" card - the piece that converts setup turns into explosive offensive sequences. Blast to Oblivion provides the heavy-hitting follow-up that capitalizes on the tempo advantages Gone in a Flash creates.
Transform cards and the instant suite provide the flexibility that defines skilled Oscilio play. Electrostatic Discharge serves as the premier "0-for-8" combo piece, while Flittering Charge and Eclectic Magnetism offer tempo flexibility and resource management.
The deck's consistency comes from intelligent cycling and resource management through carefully timed sigil activations.
Sigil of Brilliance should be prioritized for guaranteed setups, not random draws. Use Flash of Brilliance to return key sigils like Sigil of Conductivity to create embodiment tokens that unlock entire hands.
Against Control/Earth: Avoid excessive cycling - take guaranteed 3+ value each turn rather than rushing to combo pieces.
Against Aggro: Cycle aggressively to find first Gone in a Flash or Blast to Oblivion - you must race their damage output.
Against Normal Matchups: Focus on consistent value plays, using the Hamilton system to generate incremental advantages.
Oscilio requires constant life total awareness to determine offensive windows. At 10 life, you have zero turns of no-block plays. At 16+ life, you can absorb significant damage while executing combo turns.
Sigil of Solace provides crucial buffer life that extends your ability to take aggressive lines while maintaining defensive options.
Don't waste Flash of Brilliance on random Sigil of Brilliance draws. Use it to return key pieces like Sigil of Conductivity for guaranteed embodiment creation, or to set up specific combo sequences.
When Etchings of Arcana offers sigil choices, prioritize Sigil of Lightning over Sigil of Brilliance when you have guaranteed arsenal conversion. The immediate 2 damage often outweighs random card draw.
Assassins/Hate: Arsenal immediate value instants, never expect combo opportunities.
Ice/Earth: Play the value game, avoid cycling unless guaranteed 3+ value returns.
Brute/Aggro: Strip blue cards aggressively - removing their pitch resources dramatically reduces their damage output.
Midrange/Control: Balance between consistent value generation and explosive combo potential.
