I did the Prerelease on Magic Arena. Thought I had a terrible pool - all my cool strong looking stuff was in colours with just about nothing else in them. I had NO bombs outside a
Gate Colossus, with no other creatures that went over 3 power (exception; two
Steeple Creepers). I figured I had to do something weird to win. First game tried to do a 5-colour list trying too hard to exploit
Glass of the Guildpact and
Tome of the Guildpact, since I had lots of gates, and gate-finding spells, and lockets. Try to use the best of each of the stuff I had. It failed spectacularly. Then I re-evaluated my stuff, and tried to make it an Orzhov deck. I realized that Afterlife combos amazingly with
Glass of the Guildpact, since the spirits created are both white and black, plus I had two
Basilica Bell-Haunts and a
Grasping Thrull in addition to a good removal suite.
Consecrate // Consume's sac-half was a godsend, routinely scoring me big life gains while hitting their biggest creatures. My final match against a strong Simic deck packed with bombs took down a
Mesmerizing Benthid this way, which felt great.
Overall, I found that most opponents tried to play fast decks, but incidental lifegain and aggressive trading tended to work things out, while the removal was good enough to take down bombs. Orzhov decks could keep a pretty consistent thing going, and Afterlife is great (used it twice to off-set
Final Payment costs). Not a lot of reach creatures, so a beefy flyer, or a swarm of Afterlife spirits got the job done.
