Elysian Fatties Like to Draw Cards

Water of Life is a bad card, don't play it unless lifegain ties directly into your gameplan like playing a Lifeforce deck (and even then there are better options).
First Watch has a similar issue as it's card disadvantage (both players draw a card and you spent a card), and the problem with lifegain in general as a "primary effect" on cards is that it doesn't affect the board (as such doesn't slow down aggro and can't pressure the opponent) and usually doesn't help with your gameplan either (it's neither a fatty nor card advantage in this particular deck).

Cryptic Etchings might be okay in the right deck, but again - it's card disadvantage and while the card filtering effect is useful, by the time you've gained enough advantage with it to be worth a card you've probably spent 6+ mana on it and you've probably reached a state where you've effectively won. It could have a place in "relics matter" decks, but yours certainly isn't one and there are better options for that purpose.

Teleport is a tempo card (it creates a temporary advantage at the cost of being card disadvantage), which fits a better into aggressive decks than it does into slower, more grindier decks - and your deck is closer to control since you play Cryptic Etchings, Eye of Winter and Wisdom of the Elders for example.

Amaran Camel isn't a good card either, against decks that attack early it comes down too late (a 3-health blocker by turn 3 might prevent 2 damage each turn, but that's not much, and they can just Torch it since by that time they can afford the 1 mana and still play out whatever they wanted to play), and against slower decks it's just a chump blocker that might gain you some life, but a deck that's attacking with 4+ attack creatures doesn't care much about having to attack one more time.
