1) Anti-reverse time. Guard is cheap.
2) Everyone expects to see three elite chargers, so why not a little bit of a twist?
not to nitpick but i found the reasons/explanation to be odd
1) anti RT? sure you can cast it again, cheaper (by 4
cost reduction) but you should be able to cast it again if it was unupped too and frankly, we're playing PvP here, not Pvstupid-AI. UNLESS it is the only target available, theres no way anyone would want to target it instead of the unupped ones whereas upped chargers cost the same but comes with +3 damage the turn they comes into play
2) so you put a 'twist' because you knew people will be expecting 3 elite chargers? and not because it is the most optimal upgrade you could've taken for this particular deck and thus increasing its win %? i guess winning street cred from proving the community wrong is better than actually having higher chance of winning the matches (of course that doesnt matter now since jumba actually won anyway but the only reason i'm saying all this IS because jumba has won...its bad to kick someone while they're already down amirite?)
