Force Torvald to use his Recharge ability in order to maximize the effectiveness of your Energy Shield. Don't pull it out before he uses that ability. It will recharge his shield faster and your shield will be severely crippled.
Make sure you pickup Totemic Ward which gives CC immunity to anyone in your healing totem range. This can cripple a Torvald's Ultimate. Also great load against other CC champs like Cassie, BK, Tyra, and Pip Evil Mojo(Chickens).
