Whenever you scry, put a +1/+1 counter on each of up to X target creatures, where X is the number of cards looked at while scrying this way.
Whenever a creature you control with a +1/+1 counter on it becomes the target of a spell or ability an opponent controls, you may draw a card.
Elrond turns every scry into a counter-distribution engine, fattening your whole board while the second ability punishes opponents for trying to interact with your beefed-up creatures. You ramp into scry payoffs early, snowball wide and tall counter synergies in the mid-game, and close with an overwhelming counter-heavy battlefield or a few oversized threats backed by card advantage.
Add more counter multipliers (Doubling Season, Vorinclex, Monstrous Raider) and cheap repeatable scry sources (Soothsaying, Mystic Speculation, Halimar Depths) to maximize trigger density. Lean into proliferate and protection (Heroic Intervention, Inspiring Call) to defend your counter investment from wipes. For a faster clock, include evasion and a counter-combo finisher like Walking Ballista with Inexorable Tide to convert your engine directly into damage.
