When an awesome new card is printed or a new combo found, the typical response is to put that card or combo in a shell that is maximally dedicated to getting the most out of the fancy new toy. We want to stress test the unknown variable to figure out exactly how powerful it can be and if that power can stand on its own against the established decks in the metagame.
But when it comes to cards that are unbanned, their pedigree gets in the way of that process. Those that were around in the card's heyday are quick to bring up the lessons of the past and bring them into the present unchallenged, despite the fact that thousands of cards have been printed in the meantime, fundamentally changing the metagame conditions.
Perhaps this is the case with Sword of the Meek. The card made its mark on Extended in Thopter-Depths, a combo control deck that could win quickly with a Marit Lage or go long with 1/1 fliers and disruption. It was absolutely dominant near the end of that format's life, leading to is preemptive banning when the Modern format was officially introduced. When it was unbanned to much fanfare in 2016, it was mostly placed into similar shells that weren't focused on assembling the combo that quickly, so long as they could maintain parity in the meantime.
But that Extended format didn't have Whir of Invention, an excellent tutor for either half of the combo, nor was there Mox Opal to accelerate mana in a deck devoted enough to playing artifacts that it can take advantage of Whir of Invention. Both cards point toward a list that is entirely dedicated to assembling the combo and making 1/1s as quickly as possible.
To that end we have Steelshaper's Gift, another tutor that unfortunately only finds the Sword of the Meek part of the combo, but still adds redundancy. There's also Ideas Unbound, a powerful card that plays nicely with Sword of the Meek and the three copies of Lingering Souls in the deck.
With little space for interaction, we turn to everyone's favorite aggro-stopper in Ensnaring Bridge to buy time against those pesky Humans and robots. The singleton Damping Sphere is a nice bullet against combo and Tron which would otherwise be very problematic, and the Time Sieve lets you take all the turns so long as you have the combo assembled and five mana to replenish its cost each turn.
Thopter-Sword is a powerful combo, but the controlling shells it used to thrive in are a tough sell in Modern. Let's see if it can stand on its own.
