From the Future — You can't cast Spider-Man 2099 during your first, second, or third turns of the game.
Double strike, vigilance
At the beginning of your end step, if you've played a land or cast a spell this turn from anywhere other than your hand, Spider-Man 2099 deals damage equal to his power to any target.
Spider-Man 2099 is a cheap, evasive beater that doubles as a repeatable burn engine: cast a spell or play a land from exile, graveyard, your library, or an opponent's stuff each turn and his end step pings any target for his power (8+ with double strike doubling combat damage, but the ability itself uses raw power). You play a tempo-leaning Izzet shell that casts from anywhere—impulse draw, cascade, flashback, foretell, suspend—then trigger the end step ping while swinging in with vigilance.
Repeatable, flexible damage each end step that can finish players or kill key creatures/planeswalkers without attacking
Double strike + vigilance makes him a strong evasive clock that also pings, doubling pressure
Cheap two-mana body that's easy to recast and pumps into a fast kill with any power buffs
Trigger is easy to enable in Izzet via impulse draw, flashback, cascade, foretell, and casting from exile
Removal-prone: a single kill spell shuts off both the beats and the ping engine
The 'not from your hand' clause requires deckbuilding discipline—mediocre draws can leave the trigger off
Can't be deployed turns 1-3, slowing your early development
Two colors limits ramp and color-fixing depth; vulnerable to a clogged board with no evasion
With double strike already on the body, extra power turns the end-step ping into a one-shot kill.
Tighten the deck so nearly every card can be cast from somewhere other than hand—lean into impulse draw (Light Up the Stage, Outpost Siege), cascade, and graveyard recursion (Underworld Breach, Mizzix's Mastery) to guarantee the trigger. Add power pumps and protection (Lightning Greaves, Heroic Intervention, swift cantrip counters) so the engine survives and scales. For higher power, splash fast mana (Sol Ring, signets, Jeska's Will) and consider extra-combat or copy effects to multiply both attacks and end-step pings.
