So Warden great in a Landfall deck like this one, but easily fits into any White deck that runs a good amount of fetchlands, which the Warden synergizes particularly well with: playing and cracking a Flooded Strand gives you two landfall triggers to exile two cards, and you can even exile the Flooded Strand itself, putting it back into play once the Warden dies, which is a sweet (but convoluted) way to ramp in White
The timing restriction of plotted instants is a bit weird and required a few judge calls but I see how it avoids making cards like Lilah or Jace too powerful
"Merciless Rage" is headed by Anje Falkenrath, a value engine card for decks prominently featuring the madness mechanic
On the other hand, if the build is centered around artifacts, Etherium Sculptor makes things run smoother, and you can use some key combinations like Nevinyrral's Disk + Darksteel Forge to get a one-sided board wipe or rely on the Thopter Foundry + Sword of the Meek to outvalue your opponents
It makes insanely good openings, but not past that for the most part
