Well being RCB fan I might be a bit biased but I think RCB has been the most entertaining team of the IPL history (both in good and bad way)
Entertainment which was good for RCB fans
•Gayle 175
• RCB 263 innings
• VK 4 centuries in single season
• VK & ABD 215 partnership vs Mumbai
• VK & ABD best partnership of IPL vs Gujarat Lions
•RCB 200 + score in only 15 overs vs KXIP
•Countless hundreds by VK,Gayle & ABD also one by Manish Pandey
Entertainment which was bad for RCB FANS
• Bmac 158 in first game of IPL
• 3 final loss IN 2009,2011 & 2016
• 49 all out vs KKR
• Lynn-Narine 100+ partnership in POWERPLAY
•Russel's absolute power hitting vs RCB earlier this season
There have been many other big matches involving other teams but I certainly can't think of any other team which had so many historic moments by them or against them
