Sigarda, Font of Blessings

There have been three Sigardas, and each one draws its protective line in a different place. The first shielded against sacrifice; the second turned aside opposing spells and abilities. This one hands every other permanent you control hexproof, the broadest version of the effect she has ever carried. The distinction matters: hexproof stops your opponent from targeting your board while leaving your own targeting untouched, so your removal, your Auras, and your combat tricks all still function normally. What routes around your permanents is spot removal, targeted bounce, and any creature-targeting effect: those can only ever legally point at Sigarda herself. She becomes the one door left open, which makes her simultaneously the shield and the thing that has to survive, a tension the design courts rather than papers over (edicts still work, since they force a sacrifice rather than target the board). The second half is a quieter engine bolted to the body. Permanent visibility of your top card, plus the license to cast Angel and Human spells from there, turns the top of the library into a second hand that never surprises you with a blank you cannot see coming. It rewards a deck built almost entirely from those two creature types, so the draw step stops mattering as much as the deck you assembled. The pairing is genuinely odd: a hatebear-grade protective anchor and a grinding top-of-library value valve sharing one four-mana flyer, each half quietly asking for a slightly different deck around it.
