Keleseth Rogue

I have gone from rank 20 to 5 with this deck within two days with a few changes in argent commander and plague doctor, I have found that having a clear for any minion is less important than pure damage as my games are generally ending between turn 6 and 8.

Mulligan:

If you have Keleseth always keep as he is VERY valuable turn 1 and 2

If you get shadowstep in mulligan only keep if you also have keleseth or edwin

Pirates are very useful in the first 2-3 turns so always keep southsea captain and swashburglar (if you have keleseth make sure you play before a pirate to get that extra 1/1 on patches)

Deckhand is good unless you are playing against rogue mage or druid as they can hero power it away and hell be much better with a keleseth buff

You’ll usually keep Edwin unless you have no low cost cards which in that case you’ll probably want to get rid of all (by low cost i mean 2 or lower mana cost)

Replacements for legendaries:

Edwin is a very very nice early big target that can be buffed but if you don’t have him use plague doctor or another argent.

Shaku is not necessary but helps in tough situations, an easy replacement is hallucination

Leeroy is very nice and can win a lot of games but can also be replaced with another argent commander

Keleseth and patches are pretty irreplaceable so don’t use this deck if you don’t have them
