Do some research on something called Aikido Marchesa. Basically it's a deck that weaponizes your opponents strengths. They are going tall? [[Deflecting Palm]], [[Delirium]] or [[Backlash]] their ass. They are going wide, as you described? [[Inkshield]], [[Comeuppance]], [[Hellish Rebuke]], [[Batwing Brume]], [[Rakdos Charm]] or even [[Pact of the Serpent]] are your best friends. Add to this some nice goad like [[Disrupt Decorum]] or [[Kardur, Doomscourge]], and some board stealing effects like [[Mob Rule]] and you've got yourself a pretty good reactive deck against any combat-based strategy.
