Rain of Revelation

The straight comparison is Compulsive Research, the sorcery that draws three and discards, and the entire reason this exists is the two-word difference in the type line: instant. That single shift moves the card's whole strategic axis. A sorcery draw spell forces you to spend your own turn refueling, tapping out on the main phase and leaving the door open; an instant draws three at the end of your opponent's turn, holding up interaction until you know whether you need it and then cashing the whole hand of mana back into cards if you do not. The discard is the price on the deal, and here it is a flat one card with no upside attached: no land-discount clause, no flashback rider. That plainness is exactly the point, since a net two-for-one at four mana with an added sweetener would sit outside any reasonable curve. What the timing buys is flexibility: refill during a stalled board, dig for a specific answer at the last responsible moment, or convert a dead late-game land drop into fresh gas without ever committing a turn to it. It is a deliberately unadorned design whose value lives entirely in the timing window rather than in the words after "draw three."
