Igneous Elemental

The discount lives and dies on whether a land has already hit your graveyard, which tells you the shell it was built for: aggressive red decks whose fetchlands and land-dumping effects put spent lands in the bin as a matter of course. Meet the condition and you are paying four mana for a 4/3 that shocks a creature when it lands, a two-for-one that arrives ahead of curve rather than behind it. The design leans on an asymmetry worth noticing: the enters-the-battlefield ping is fixed regardless of what you paid, so every mana the discount shaves off is pure profit against the same body and the same removal. That makes the card a barometer for how well a deck manufactures a graveyard land early, and it punishes durdling: cast it off the top before you have cracked a fetch and it is a clunky six-mana glorified two-damage burn spell on a fragile frame. It belongs to a small family of red creatures that pay you for treating incidental self-mill from an aggressive manabase as tempo instead of setup. The ping being optional, and pointing at any creature rather than a fixed slice, keeps it flexible: aim it at a mana dork, a hatebear, or nothing at all, whichever the board actually asks for.
