Counters to new reworked champs and items
(these are just ideas, many have worked for me in bronze, but i am not guaranteeing any success)
Champions:
loses easily to early poke/harass (continuous as to stop his passive, best is probably and sadly 
for DOT poke), ganks, heavy cc, %health, and escapes
loses to invincibility 
since he cant ult them to death (hard to dodge with fizz but is possible to delay and escape). Also loses to healing, %health, silences and spellshields since he is a burst with abilities DOT ad.
loses to poke, heals, %health, slows, and escapes. Also if he is with a support without an engage that hooks like
or 
it is hard to snowball with kills.
loses to hard cc, %health, vision, spellshields, movement speed reduction, counter jungling, 
, and ranged harass. He isn't unkillable especially if he is alone.
loses to focus and cc. armor helps, attacking when riposte is down or baiting it.
loses to mobility, cc, regen and sustain, overconfidence (all riven mains are), and 
. Yes malz can stop anything riven does with his q and ult. He has ranged poke and although he cant escape, if he is cc'd his passive and e still hurts, be careful before level 6 since she can all in easier than he can, use this time to farm with e/passive combo and q her for harass while staying a relatively safe distance away and near a tower.
Items:
: basically attack speed reduction. 
all help.
: More Armor and maybe some movement speed increasing items to stop the poke
