While I personally like direct removal spells, this can become useful in mono-blue decks that otherwise dont have reliable answers to threats
With cards like Hellrider kicking out other recent four-drops like Moltensteel Dragon (which is actually a four-drop) and red getting more curve-toppers like Thundermaw Hellkite and Zealous Conscripts, RPTS is another card that was better years ago as it was a curve-topper that could be supplemented by another three or four mana spell at the top of the curve when you alpha striked
The Mana Base The deck runs mostly fetch and dual lands like bond, tango, and shock lands
Entering with six whole loyalty counters, plus a passive ability to generate advantage, plus threatening removal and it makes its own blockers
This two-mana instant spell lets you destroy an artifact or have a creature you control deal damage equal to its power to to an opponents creature
If your deck and/or sideboard include multiple copies of Built Bear, you can circle different options for each Built Bear as long as the choices for each one are clear and understandable to all players
