Archangel Elspeth Archangel Elspeth doesnt really give us anything that we havent seen before in a four-mana white planeswalker
Depending on the Secret Lair in question, this has to be a split recommendation
Another example is the two-mana Ronom Unicorn that doesn't need to tap or use mana for its sacrifice, although it cannot hit artifacts
In all other zones, its power and toughness are 13
Channel and Sneak Attack don't have similar rules text, for example, but they overlap in their ability to do broken things with big colorless creatures, so you might pick up a Sneak Attack to support your early-pick Channel, and then prioritize the legendary Eldrazi creatures, Blightsteel Colossus, and Sundering Titan over a card like Karn Liberated, which only works with the Channel plan
People generally feel, if they had a chance to compete in the game, or to at least break up the combo, it's OK
